safe sex

I'm a virgin, and this really attractive known fuck boy in my school has admitted to wanting to have sex with me. And I'm considering it. The only problem is we've never actually talked in person. I don't really care if people are going to call me a slut. This is my senior year of high school and I want to have sex. I am also not on birth control yet. So if I do this, I need to know everything and anything you can tell me about having safe sex.
