First time Sex Questions? ( Answer Please? )?

Condoms are moderately effective against pregnancies, and according to studies, only 15 out of 100 couples will get pregnant by using a condom. Also, is your girlfriend on birth control pills? That's also a contributing factor if you are concerned about her becoming pregnant. Good luck with everything!
