okay i have unprotected sex all the time and the last two times my boyfriend has ejaculated in me it burns my inside walls... and it feels like a pinch or something and it hurts bad.. i dont understand what it could be we didnt do anything different and i kno this isnt normal because we have been together for 5 years and always had sex and nothing like this has happened.. and it doesn't burn when i pee... so it CANT be a yeast infection right? because ive had those before and i kno what those feel like so it cant be that and we havent used different soap or anything to was down there, so it cant be a fragrance thing... can you please help me im so confused. i mean i can stop the burning by him not ejaculating in me but theres still something wrong and i'd like to figure out what it can be.
