AIDS is such a serious issue. You've have to be either stupid or just not caring to have unprotected sex, especially with a partner you don't know or trust. I've seen what aids can do to people have a couple friends that have it and one that has died from it. It's not a pretty sight and it's hard on not only that person but all their loved ones as well.
Anyways, I'll be the first to admit that as a teen I wasn't always as responsible about it as I should have been (I think that as a teen, I was just an idiot that didn't care....not to say all teens are this way....just that I was)...but fortunately for me I was also lucky enough to not get a STD. Today, I take sex very seriously. I don't jump into things the way I once might have as a teenager and when I do get into a sexual situation all precautions are taken.
