After going to the bathroom I came back and found that Don was just about to start his lesson. I quickly sat down next to Raph and Don began his lesson.

"Right well today I'm going to tell you about the penis and how the hormones are involved with it."

I bet you'll never guess what picture came up on the board...a penis of course. I could just sense the tension between them all. Don continued anyway

"ok we are looking at the sexual organs of the penis. Let's start at the bottom of it. This is of course the penis it's used for having intercourse."

I looked around quickly and found Raph sort of paying attention, Leo finding this fascinating and Mikey...confused.

"So what's intercourse?" I smiled and replied

"intercourse is a posh way of saying sex."

"Oh I get it." When I looked back at Don he looked really happy, probably because they were listening.

"Anyway, on top of the penis is the foreskin, it helps protects the penis. Then we have the scrotum, a bag containing the testis. The testis which produce the sperm and the male sex hormones. Can anyone remember the name of the male sex hormone?"

What I saw next I thought I would never see. All the guys had put their hands up eager to answer. Don picked Raph and he said

"ain't it something like, Testosterone."

"Well done Raph your right." Raph smiled smugly feeling proud of himself.

"Anyway the sperm travels through the spectrum or sperm tube and goes into the seminal vesicle. That stores the sperm and releases it when necessary. Finally if the man is having intercourse the seminal vesicle will release the sperm and it will travel through the urethra, which carries the sperm and it will be released out of the penis. Now are there any questions?"

Leo put his hand up and asked "what about when he goes to the toilet?"

"Good question Leo, the bladder has the urine and when he needs to go it comes out through the urethra and out of the penis. Oh and sperm and urine mixed together is called semain."

"yeah yeah it's all good n' stuff but can we go now?" Raph asked rather impatiently. Don smiled

"yes you can go now for a little break, you guys deserve it."

They all ran off to do what they wanted to do while I went up to Donnie who was smiling from ear to ear.

"I can't believe it went to well, it's a miracle."

"See I told you they would back down eventually. Well my turn after break. Want to get something to eat?"

"I would love to Miss Smith."

A/N: Finally I got one out. I'm afriad due to the horror of school that I will only be able to get stuff out on the weekends so I apolagize. Anyway I hope you liked it. Big thank you to all the people who have reviewed it. Love you all. :)
