Hi, I'm sixteen, 5"2, and I haven't got any medical history. I gave my boyfriend a handjob and his cum hit my thigh, but I had my underwear on. I read a lot of articles online that sperms will still be active when it comes in contact with any lubricant. I'm uncertain if the cum touched my underwear or my vagina, but I wanna make sure if I might get pregnant. I washed off the cum with water afterwards tho, does that help?
