Okay so me and my boyfriend have been together for about 4 months now, and when we first started having sex everything was fine. I have gotten many yeast infections and UTI's because I hold me pee in, I have no idea why. But anyway, after about a month after having sex, it started hurting really bad and I didn't know why, it still is to this day and I don't know why. I have been tested, I was tested in February and I just got tested the other day.
