Hi, confused girlfriend here! Im 18 but grew up in a house of women and am a late bloomer so didnt really learn a whole lot about boys and foreskins etc so desperatly seeking advice!

My boyfriend is 19 and I dont think he has ever pulled back his foreskin, al least not when masturbating or having sex. We have been using condoms for the last year and a half and he always put the condom over his foreskin and that was fine, never got me pregnant or anything, now iv gone on the pill and im soo confused

does he have to pull back his foreskin before we have sex? How does this whole thing work?? He was my first and only sexual partner so I've no experience whatsoever and i dont wanna ask him for fear of sounding stupid...
