An Important Day

Well ladies... I lost my virginity this Labor Day Weekend. I lost it Friday but I wouldn't really call it "sex" it hurt way too much to do anything, but today it felt so good!! It was my boyfriends first time too.. However I'm a little concerned he said Friday he may have pre-cummed (pre-came) inside me and he didn't have a condom on. He's concerned I'm gonna get pregnant because of this. What are the odds I'll get pregnant from pre-cum? And today and Friday there wasn't any blood so we're thinking my cherry hasn't been popped. Is it true there's like tons of blood when a girls cherry is popped? Today he did have a condom in and he pulled out so I'm not worried about today. Thanks for your help ladies! Also what's it like to orgasm because I'm trying to but I don't exactly know how...
