Every time I have sex with this particular person my vagina burns like hell for a good 30-60 minutes and hurts like hell to pee after! What could be wrong? Am I allergic to his sperm?? This didn't happen with my ex so I know it's my current SO but I don't know what could be wrong this happens EVERY TIME. I even take breaks from sex with him to see if the resting period will help my vagina but it doesn't matter it burns EVERY TIME and sometimes swells like it is right now. We don't use condoms. He's very thick and has to slowly enter to avoid tearing me. I've been tested several times and all I ever get is a UTI. So I'm pretty sure it isn't an STD or any other STI. (I currently am taking meds for my UTI and yes I know I shouldn't have sex with a UTI) that's beside the point because even when I don't have a UTI this happens. Please don't judge I just want some honest opinions I'm making him get tested because he said he has never been tested before.
