Pinkie sighed as she stepped in the little dragons room, he was sobbing into his pillow, "I'm sorry I had to spank you Spike but-"

"You didn't have to send them all away!" Spike snapped, glaring at the party planner, "We'd been looking forward to this all week!"

Pinkie sighed, "I'm sorry Spike, but after that confusing game the girls made you play I think it's better if you spend some time away from Button Mash, and the girls needed their parents to explain to them why what they made you do was wrong,"

"That was SOOOOOOOO embarrassing!" Spike wailed, "You had me marching in shame, door to door, and telling everypony about my first kiss!"

Pinkie's eyes widened, "That was your first kiss?" but Spike didn't answer, "I'm sorry Spike. The girls really shouldn't have made you give up your first kiss like that. That moment should be special. It should be with somepony you really like,"

"I... kinda liked it," Spike muttered.

Pinkie groaned, "I know you're confused but Stallions kissing is very very naughty,"

"Mares kiss each other all the time!" Spike glared.

Pinkie sighed, "I know they do, and I agree it's not fair, but it's a Stallion's duty to... to only kiss girls,"

"Eh?" Spike blinked.

Pinkie sighed, "I know Twilight doesn't want to have 'the talk' with you yet so... Let's say it's a Stallion's duty to only kiss mares because kissing leads to marriage and marriage leads to foals. You see, Stallions can only have foals with a Mare, not another Stallion,"

"How come?" Spike blinked. Even in his distraught state he was still eager to trick Pinkie into revealing the secrets of life.

Unfortunately Pinkie didn't fall for it, "Stallions just aren't built to get pregnant. Twilight will explain why when you're older, it's just boring anatomy stuff,"

Spike pouted.

"I'm sure you've noted there are a lot more Mares then there are Stallions. The reason mares can choose each other is because most will never even get the opportunity to even date a Stallion, much less marry one, because of how few boys there are. That means many mares have to marry another mare if they want a special somepony. However it's a Stallion's duty to marry a Mare and have as many foals as possible. If even a small number of Stallions married other Stallions then they couldn't have babies.

"Our population wouldn't grow very fast at all then and it's almost guaranteed even fewer colts would be born. That goes on for too long and ponies, as a species, will die out. It's not fair and it's not even right but it is necessary. Necessary for our species as a whole. Stallions can't be selfish and choose another Stallion, not when faced with the survival of our entire species.

"Stallions have completely equal rights in everything else. You can choose to marry any mare you want... but for the sake of our species it has to be a mare,"

"But... I'm a dragon," Spike pointed out, "Not a Stallion. That book on dragons I got in Manehattan's Dragon Town said I could get pregnant,"

Pinkie sighed, "I know," Twilight had told her. The book worm was always eager to share new knowledge, "But that doesn't mean you should, at least not with a Stallion. If you choose a male dragon nopony will mind, but Stallions are precious to us. We need every one of them to do their part. Honestly you might even get in bigger trouble because you're a dragon.

"If you had hybrids with a mare nopony would care. They would even congratulate you because you gave a mare a child when they usually couldn't have one... but if you choose a Stallion... things will go very bad. You'd be seen as preventing them from having a pure blooded foal. You'd still be taking away from the pony population no matter how many foals you had. After all, your foals wouldn't really be ponies but a new species of their own.

"Not many Mares would mind having hybrid foals but that's because they would never have the opportunity to have a pure blooded foal of their own... but then you're children, regardless of their gender, would never be all to marry a Stallion either...

"I'm sorry Spike but that is how life is, not everything can be as great as a party,"

"... You ruined my party," Spike accused, not seeing passed that for anything else she had to say.

Pinkie, for her part, flinched, "I know I did, but some things are more important then parties," she brushed away Spike's tears, "Hopefully you'll understand when you're older,"
