my vagina about 3 days ago burned when i went to go pee after having sex with my boyfriend & yesterday again it started to burn when i peed after sex. I noticed it is a bit red & has a few pimples (they look like ingrown hairs) in the lips of my vagina... no weird smell or discharge (it’s regular white/clear). It only hurts when I go pee after sex? i don’t know if we’re going to rough during sex or if he’s sucking to hard when he gives me head? or maybe i’m having too much sex? I also masturbate often (I use my shower head) I don’t want to go to the doctor... the pain is not every time i pee only after sex but it does burn, idk if should wait? or go get it checked out? or if it’s normal because i just started having sex? help!

P.S. I just started having sex this year in February. My boyfriend is the only person i have been with and we ALWAYS use a condom. I am not on any birth control
