Amy looked at Sheldon's blue orbs and he smiled warmly as she hugged him. Like other scientists, Sheldon believed that passion, based on science, could only be explained by a disturbance in the central region of the brain where those responsible for sexual desire are located, which serves only to reproduce the species. But now, ironically, he loved a brilliant brain specialist. And she is also responsible for the research that denied love at first sight, which impressed him a lot when they met, because he had read the research and agreed with every semicolon. On the subject, Leonard once told him not to lose her. Leonard was right when he remarked that without Amy his life would be like space dust floating through the galaxies.

Amy felt Sheldon's hands slowly inching around her waist. When her fingers pressed a little, the skin shivered. Second by second Amy experienced a new sensation and her whole body responded in different ways. When Sheldon slid his hand to her hip, Amy reopened her eyes and pulled her mouth away in a totally unexpected gesture.

"Did i do something wrong?" He asked with a naive expression.

"No, you didn't do anything wrong, Sheldon!"

"Then why did we stop?"

Amy sighed.

"It's okay if you want to give up!" Sheldon offered understanding.

"No! I really want to be with you tonight!" Amy encouraged him: "I want to keep going!"

"Are you sure about this?" Sheldon insisted. He could be many things, like a not-so-devoted friend, but Mary had taught him to be a gentleman with women.

"Yes I have!"

Sheldon's eyes gleamed.

"I want to be with you too!" he said passionately. Sheldon wasn't lying. On the contrary, he was surprised that he wanted so badly to be there in bed with her.

"So kiss me!" Amy requested and waited.

Sheldon leaned down and touched her lips with his lips; they were damp and smelled like wine. Some time later, Amy took the initiative to hold a part of the nightgown and began to take it off before the calm and peaceful look with which her boyfriend followed her movements. Once the nightgown was over her head, Sheldon felt his throat go partially dry when he discovered Amy in just her bra. Suddenly, the scientist inside him discovered a very interesting fact: as a man, he needed much more than just to observe her. His hands wanted to confirm the symmetry of her breasts, but where should he start touching them? Sheldon felt the rare chagrin of not having the answer. Fortunately, Amy knew him very well and identified the impasse. She read in his expression how much he wanted her and at the same time an internal question confused him. Anyway, Amy hugged him gently to encourage him, smoothing things over with comforting affection.

Silently, Amy lay back on the pillow and Sheldon followed. Eye to eye, this was a special development for them. No words would be able to describe the emotions that both felt mutually. Including heavy breathing and a racing heart, Sheldon transferred his kisses to Amy's chin and then to her lap. Amy closed her eyes and concentrated on how each impulse pleased her immensely and gave her the opportunity to enjoy a new adventure like the books she read hidden from her own mother.

His hands made soft gestures when touching any part of the body. Every time Sheldon encouraged her, her heart automatically confirmed what her friends said at girls' night out. Sex is better than chocolate, better than a glass of wine, better than opening a brain and everything in between! Amy agreed thoughtfully while smiling discreetly in happiness. Without a doubt, making love to the right person was the best part.

For long minutes, Sheldon dedicated himself to kissing her all over and, by the sounds that the birthday girl made, his IQ of 187 concluded that he was doing everything right, as Penny explained. As a man of science, Sheldon was fascinated by everything he was discovering. Contrary to his theories, the female universe turned out to be more promising than he thought. All of his emotions were well defined as he studied Amy's reactions. For example, sometimes she would bite her mouth and sometimes she would grab the sheet and squeeze hard or her back would rise involuntarily. Hard to say what she didn't like about the foreplay!

After a considerable amount of time, where Amy was on the verge of euphoria, Sheldon announced that he was going to take her panties off and asked if Amy was okay with it. With a nod, she nodded.

"Everything is fine!" Sheldon looked at her one last time and then, using his fingertips with surgical precision, began to pull down her panties. Meanwhile, Amy was staring at an insignificant part of the ceiling. His heart was beating wildly inside his chest. She was nervous!

The seconds passed and there was nothing hiding her body anymore, just an understandable shyness. In order not to break the ritual that guaranteed order, the lingerie also had to be properly stored like the rest of the clothing. After taking care of this detail that required satisfactory organization within the bedroom, Sheldon turned his full attention to Amy and finally managed to give her what Penny called "women's heaven." It was the first time, there was no manual that could help him, but luckily he remembered Penny's teachings thanks to his excellent memory. Sheldon cared about what the woman he loved was feeling, even if he wasn't good at deciphering the visible signs.

"This is really, really good!" Amy made a delighted sound mid-sentence, which made Sheldon happier because he now knew with absolute certainty that Amy was enjoying herself. Several times, the way she reacted and spoke gave Sheldon an understanding of when to stop or continue, so he extended the foreplay as long as necessary.

When Amy decided to end the intimate kisses, she reached up to pull him back into her mouth. Sheldon lay down on top of her and they exchanged some more caresses. Moments later, her body was on top of him, kissing him where she wanted because she had permission. Her touch, the way she ran her hand and her mouth were extremely new to Sheldon, and he wanted to understand just how susceptible the human body is. Until an hour ago, the ego considered him a genius whose brain, his most prized possession, would be able to excel without intercourse. Currently, his brain had reduced to nothing more than a victim of oxytocin. And to top off the decline, he was enjoying it!

"I love you, Sheldon!" She whispered before running her fingers through the hair on his chest, making him shiver with a sudden bout of cold mixed with a rush of heat.

"Oh gosh!" Sheldon spoke without realizing it, just verbalizing the first word that came to mind.

When it was Amy's turn to undress him, Sheldon felt another small shiver run down his spine and disappear at his toes. Silently, like a little lamb, he lay there as he compared himself to a toy whose girlfriend took him out of the package. Half a minute later, the poor scientist felt his pulse quicken and it continued to quicken. When Amy touched his genitals, it felt so good that he tried to call her name but couldn't speak, and pressing his lips together, Sheldon fought the inner agony; an incredibly good agony that he had no idea about. He tried to gather his strength and remain rational, instead he hit his head on the pillow and whimpered as a longing caught in his throat. Her boyfriend's unexpected reaction made Amy guarantee that he would continue moaning for a while longer.

"Please Amy, stop this. You're killing me!" Sheldon's voice was nothing more than a futile attempt at resistance. His fragility in being virile like any other man was making him drunk and without air to breathe.

"Do you really want me to stop now?" Amy asked, dodging over his chest. For a moment, Sheldon wet his throat with his own saliva and struggled to speak the truth. The truth is that he was without answers!

The silence in the bedroom continued for a few more seconds and joined with the only light on, which gave the environment an aspect of comfort and privacy. During a new kiss, Sheldon moved his body without repressing her expression of surprise. He laid her down on the pillow and enveloped her like a sudden storm. Seeking authorization in her green eyes, he saw her agree with a slight nod that gave him complete freedom to proceed without any hindrance. Gradually, the silence was broken by Amy's voice emitting sounds of pleasure and pain. Pleasure when Sheldon closed his mouth on her breasts and then pain when he started to penetrate her. But realizing in time how difficult it was for Amy, he stopped.

Sheldon showered her with affection and sweet words. Even so, Amy was still trembling in his arms. So he let her breathe to feel safe before making another attempt. Both knew how challenging it could be, after all, it's the first time for both of them. While Sheldon respected the boundaries, Amy grabbed him by the shoulders, which somehow calmed her down.

"Sorry!" Amy babbled. In his green eyes was contained a singular truth, at the same time that fear was seen in the depths of his pupils.

"I understand! According to the book Leonard gave me last year, losing our virginity is harder for women than it is for us men!" His explanation was obvious, but it made Amy smile. At times, Sheldon was so understanding and so thoughtful that he felt like a different person. But that was just an important part of his personality; the plot that led Amy to fall in love.

"Thanks!" Amy caressed her boyfriend's face.

"Is it okay if we try again?"

"Yea!" Amy answered and Sheldon adjusted his position on the bed. Two, three, four tries before he finally got it. When he did, Amy held him against her chest and squeezed her eyes shut. Sheldon also felt slight discomfort when inserting the entire penis; the maneuver also made him close his eyes, briefly.

"Are you okay?" He worried when Amy didn't open her eyes.

"Weird, but I'm fine." Amy couldn't describe that feeling. "And how do you feel?"

"I think I'm fine too!"

"Did you feel pain?" Amy wanted to know. Perhaps it was his scientist side showing.

"I'm feeling level three pressure, which I know is perfectly normal!" He did a cursory analysis. "And your pain?"

"Decreasing."

"Alright then, let's continue! You tell me when to stop."

Sheldon started over and was the first to get used to it. Amy was the last to feel more comfortable, but after that she felt almost no more discomfort. This made Sheldon gain confidence to switch frequency, power and speed. Following his own instinct, he loved her and gave her her first orgasm much sooner than expected. For Sheldon it was a fantastic discovery of all the sensations around his body. He didn't know how to describe in a single sentence the incredible experience of making love. And when Amy relaxed, he accompanied her movements, each at a different time and with alternating intensities. Happy with his own discovery, Sheldon continued telling her how much he loved her as Amy tried to catch her breath.

Five years after they met in a cafe as a result of a prank by Howard and Raj, Amy and Sheldon were making love. And Sheldon was still surprised that he was enjoying it more than he thought. Throughout his life, whenever he came across the subject of "physical intimacy", he never had the curiosity to try it out, for obvious reasons. Day and night, he devoted himself to science and games with friends. Looking at it from a new angle, since he was now having a physical relationship with Amy, there's no denying that the only conclusion remains love. Only love could make him change his mind! The love he feels for Amy is now reflected in his gestures during intercourse. Sheldon is careful not to be rude or rash. He remembers Penny's words about satisfying each other instead of worrying about yourself. Maybe that's why Amy's expression changed. The pained expression has been replaced. He's not good at guessing people's emotions, but he dares to say that Amy is enjoying it as much as he is, and to prove the theory, there are beads of sweat forming on his temples... and lingering moans between his lips too!

The light from the lamp, the bedside table, some books neatly arranged on the shelf and the clothes folded on the chair next to the bed make up the room. Amy's eyes close and open without her noticing, it's like wanting to master sleep. It's stronger than anything, it's impossible! And Sheldon has a feeling she's going to start screaming. Still under the spell of the imaginary screams, his gaze fixed on her mouth, waiting for the moment when they would become real. Not even in her wildest dreams had Amy come close to conceiving this feeling. Things got better because Sheldon wasn't just any man, he was the man she loved, consequently the first and last love of her life. Behind closed doors, Sheldon proved to be a perfect boyfriend; in his naivety he managed to surprise her, maybe Texas gave him a little hot blood.

The two discovered what they liked and disliked in a sexual relationship. The bed has turned into a research lab, albeit indirectly. Sheldon discovered that he likes to get kisses on the back of the neck. Adding bites turns him on. He also had the opportunity to confirm how much he hates looking at his feet. But what surprised him most was the discovery that Amy likes spanked. He finally understood why she seemed to enjoy the punishment when her lie was exposed a few years ago. At the time, she said she was sick when, in fact, she wasn't. Who would have thought that the eccentric Dr. Was Sheldon Cooper a potential lover in bed? Unanimously, Amy got the best birthday present of her life. Nothing needed to be said about it; a single glance would be enough to identify emotions she didn't bother to hide.

Almost two hours later, in an apartment in Pasadena, intercourse crossed the last borders and approached the fort where the reward is visible on the face. Sheldon was stunned by the indescribable pleasure found at the end.

"I have to admit: I didn't see this coming!" Sheldon confessed lying on top of Amy, burying his nose in her neck.

Amy just replied with a satisfied smile, taking the opportunity to put her hands behind his head for a while longer. She felt his legs between hers and she could stay like that for as long as it took, it didn't bother her that the sex had increased her hunger.

"I love you!" Sheldon lifted his face and looked at her with unmistakable love.

"I love you too!" Once again, Amy was sweet in declaring herself to Sheldon. The statement warmed his heart.

"Good to know!" Said a happy Sheldon. "Now I need to go to the bathroom." Sheldon announced, rolling onto his side. The condom was bothering him and he needed to get rid of it.

Amy was still panting when he left her on the bed to go to the bathroom and returned minutes later. The sight of Sheldon without clothes on pleased Amy, especially his nice ass. With a smile on his lips, Sheldon slid under the covers and took her hand. He looked like a new man, and she certainly felt like another woman.

The newly ended coitus allowed Amy to still feel Sheldon's weight crushing her body, it was as if closing her eyes brought everything back. His legs were still weak. Her mouth couldn't handle her rapid breathing. The messy hair on the pillow gave clues to what they'd done in bed. She had a lot of things to say to him, but at the moment it was impossible to smile, speak and breathe at the same time.

"I liked it more than I thought I would!" Sheldon's observation brought a new paradigm. In fact, he was feeling light as a feather. And interestingly, there was nothing wrong, no points to be questioned or noted or bad reviews. Nothing, just an inexhaustible source of joy.

"Me too!" Amy was bursting with happiness.

"I hope your next birthday so we can do it again!"

"It's fine by me!"

"My goodness, I'm so hungry! I knew sex would whet my appetite, but I'm dying! It's like I haven't eaten in days. Interesting!"

"We can have dinner here. What do you say?"

"Don't you want to go to a restaurant?"

"I think I prefer to order over the phone, that way we save more time!"

"Okay, it's up to you, it's your birthday! ..Do you want pasta?"

"I think it might be!"

"Chicken with tangerine is a good option..or Pizza or..."

"Sheldon?"

"Yea!"

"Thanks for this." Amy squeezed his hand. Clearly she was floating on clouds.

"No need to thank me. You deserve it for the patience you've always had with me. I know how annoying person I am, so I thought this would be the best gift I could give you in return."

"You got it right, I loved it!"

"I know, you scratched my back."

"Oh I'm sorry...I didn't mean to..."

"Okay, that's a good sign. According to the kamasutra, the woman is experiencing pleasure."

"I can't believe you read the Kamasutra!"

"Of course not! This book is completely idiotic."

"Then how do you know?"

"I overheard Raj in a conversation where he was trying to get a girl."

"It worked out?"

"My goodness, of course not! We're talking about koothrappali!"

"You're right!" Amy smiled. "Sheldon?"

"I'm listening!"

"Would it be too much to ask for you to sleep here with me?" Sheldon was silent. "You know, I would love it if you would sleep over at my apartment tonight!" Amy added, turning sideways on the bed to face her boyfriend.
