So recently I've been experiencing a burning sensation whenever my SO and I try to have vaginal sex. Only when he sticks his penis in does it burn. It doesn't burn when I pee or wipe down there or anything, ONLY when he sticks his penis in me... Now I had something similar happen and I was treated for an intravaginal bacterial infection (some sort of yeast infection) and it went away and was fine. I went to a different OBGYN and this guy was an idiot! I'm awaiting results for an STD panel but me and my SO have been together a year and a half and I'm 100% certain we have been faithful. I've never been tested before though, despite being sexually active for years. No one ever informed me about sex, precautions, anything... Is it possible I had something I contracted from a previous sexual encounter it just hasn't shown signs for over a year? Also if it isn't an STD... What the heck could this be????? It only has that burning sensation when he actually is inside me, he doesn't have to move or anything so it's not friction related. The doctor said he would give me yeast infection medication just to see if it cleared it up but he never called anything in or gave me anything. Help??
