A couple days ago i gave my boyfriend a ha****b, but he wanted to finish off by watching me masturbate. so, i hurried off to wash my hands and between my fingers with cold tap water, and dried them off with a towel, but i didn't use soap. now i'm getting super paranoid wondering whether i washed them thoroughly enough (i know i should've used soap, but it didn't occur to me at the time!!) and i'm scared what if precum was stuck in my nails and maybe i could get pregnant from that... (i had my fingers up there for 10 seconds or so)... does anyone know whether i could get pregnant from this??? help!!!

also, should i get plan B or something similar to this???
