Why Do You Want Sex?

So.. This is mostly for the younger people. (Anyone under 16 really) why do you want to have sex with someone? I don't really care that you do, this is mostly to just understand because I see a lot of posts about "giving head" "young and having sex" "can I get pregnant if.." Etc. Following those posts, there's often the comment of "you're too young". So.. Why do/did you want sex at a young age? (I'm saying under 16 cause 16 is often the age of consent ) did you regret it? Is it worth it?

Personally, I have a friend who first had sex at 14 with someone who was 19. A while later she completely regrets it and regrets most of her relationships in the past couple years.
