hi.. ive been sexually active for the past few months and ive been with a few differents guys. none of them have anything that i know of. after i have sex with someone my vagina gets really raw and starts to itch and burn really bad. the past few times ive used the bathroom its sorta hurts to go too. and ive noticed 2 microscopic bumps around my vagina and they itch.. the thing is tho is it doesnt itch all the time. should i go see a doctor or is this normal? could it just be tht im not use to having sex and it itches cuz its being stretched an torn? and are the bumps just cuts? please give me advice!
