Every time my teacher talks about sex in health class, I get really nauseous and queezy. Why?

Whevener my teacher talks about the male reproductive system, and we get into the topic of semen, sperm secretions, and ejaculation (etc.), it disgusts me and I feel I am about to vomit. It's worse than anything I've expirienced before.

Why am I so sensitive to the subject of male sexual reproduction?

Well, spuging is pretty gross.

How old are you? If you are young, you are probably not used to the idea.

I don't think it is really anything to worry about. Don't try to NOT think about it. Explore the idea in your head and don't let your emotions rule.

I feel this way about drawing blood. I nearly pass out. But, it isn't something I need to deal with on a regular basis either.

Honestly, though, you should talk to a counselor about this if it continues. Ejaculation is a part of healthy and happy relationship. If you are unable to accept this, you will find intimacy very hard to deal with.

Depends on how many times you've heard about sex-related issues. Teens generally feel that way. Probably you need to ask your professor if the class is right for you.

you mean they have to repeat the same lesson?

Well is your teacher male or female? Young or old? It could just be who is talking about it.
