I had and I don't want to get pregnant? Also scared of STD?

after youve already had , there is no helpin you not get pregnant. if you are then you are. plain and simple. kinda stupid not to use a condom on your first time much less any time. birth control pills are 99.9% affective but needless to say i know many many girls who have gotten pregnant on them. if he doesn't have an STD then no you cant get an STD from him. you sound like you need a lot of research in this area.
