birth control???

soooo ive hooked up w my ex multiple times (he’s fingered me i gave him a handjob) and he keeps talking abt how he wants to fuck me. today i wasn’t expecting to hook up so when he offered to eat me out i was uncomfortable and said no (which he respected) but now am wondering if i should’ve said yes. anyway he told me to go on the pill which is a good idea (but im not only doing it for him) but how do i talk to my mom abt it? she thinks ive only kissed one guy once. ever.
