Yes, sex should mean something, but if you want to just do it and stop waiting for "the one" then do it! I actually waited until I was 19 to lose my virginity. My first time was with a guy friend of mine. I was sick of waiting for "the one" and wanted to just do it already! I don't regret doing it the way I did it. I knew the guy, I was friends with him and I was comfortable with him. Hooking up with a complete stranger isn't something I would have done, but some people have no problem with it. I've never had a one night stand. For the first time, I suggest doing it with someone you know. A friend you are comfortable with.
