Sorry kid, I have read some of your posts, and you are well ahead of most 15 year olds, but you are the victim of years of public education STD brainwashing. What they teach in school is something like, STD=Death, unless condom, then 100% safety. That's bogus.
HIV influences our idea of STDs, but HIV is actually pretty rare. If you're not doing street walking hos or other dudes bareback, then you're probably not getting hiv. Like I said, more people in the US died of staph infections last year than AIDS. The reality of STDs is that they are actually very common, and most of them are really no big deal. And yeah, I do speak from experience. I've had crabs - which I caught without having sex, believe it or not, a skin virus called molluscum contagiosum, and also like I said, I was married to a woman with herpes, both types, and never caught it. Also, anyone who is sexually active will carry the HPV warts virus - I bet I've got that one, too. And do you know what? It's really no big deal. If you want to have a healthy sex life, you need to get over your STD fears.
