I don't. I got curious about it a few years ago, in fifth grade or so, and I looked up all of my questions on google and wikipedia. At THAT point it made me uncomfortable. But after seeing people talk about it, and realizing that it was just natural, I am totally fine with it. My friends are sqeamish on the topic, however. Afterall, we're in seventh grade.
It's quite annoying, actually. I was talking to one of my guy friends and he called me a deauschbag. I don't think he knows what it is, and told him it was nearly the equivalent of me calling him a condom. Then he totally freaked out and got all red. I mean, sheesh. It's just a little peice of latex! However, one of my friends doesn't really know about it, and tries to subtly ask me questions to increase her knowledge. I like meeting people who aren't afraid to talk about it. Things like abortion, sexual orientation, virginity, sex before marriage, etc. I enjoy discussing serious topics. But I laugh as I imagine my freinds responding to the word p***s, or orgasm, let alone SEX. Hehe.
