Ok so i'm an 18 year old college student. I've sat through all the sex ed classes in high school and i have no intention of going all the way with a man, however my Bf and i have recently gone rather far and i'm starting to worry. Last night we were in the back of his car and he had cum in his pants, i'd kept a good amount of space between us while he did, however after he had cum he used his hand to clean himself off and well... i licked his hand clean after. I know that shouldn't cause me any problems, but what follows worried me. We do this thing where if one of us gets to cum then so does the other and it was my turn. My question is, Having licked his hand clean and the fact that it was well below freezing, because he fingered me after, could i get pregnant? I'm probably worrying over nothing, but I have my whole life ahead of me and i don't want to be a mother just yet.
