How do you know your ready to have sex? I'm a girl and I 'm taken by this guy and I don't want to be peer pressured. But he said he wont pressure me. So I think I can take is word. But usually on movies and tv or in real life after you have sex and in the morning its called bushy tail? Or something like that. Its when your all smiley and giddy. Whats it called? And i'm only 15. I'll be 16 in June.
