Last Friday my bf and I before having sex he wanted to foreplay by allowing his penis and my vagina touch. Afterwards, he asked me if its was okay to introduce his penis but he will pull out quickly because he know i get nervous, I dont Want to get pregnant. Anyways when he pull out few minutes later  (2 min) he had white vaginal discharge on his penis. Whats this? In concern . Anyways, Im freaking out waiting for my period. Can i get pregnant? My bf didnt ejaculate nor he has precum.
