iv only had sex once and we used a condom it was on july 21st and im pretty sure i had this bump on the lip of my vag...but closer to my leg. anyway im thinking i had it before that day BUT im not certain. i think i may have gotten it from shaving. usally when i get bumps from shaving they go away but this bump has been there for a month i guess like 34 days maybe a little longer...it doesnt hurt or itch but its still there and i want to make sure i dont have a STD. its just one bump by the way.
