Hi, i'm female, and mid 20s. I am sexually active, but hadn't had sex in a few months until last weekend. My vagina is now feeling really tensed up. I don't feel anything after sitting down for a while, but when i stand up i feel my vagina is incredibly tight and i feel i need to pass urine, even if i don't. It is not sore when i pass urine though, so not sure it it would be a urine infection. But it does feel a relief, only for a second, when i pee, not matter how small the amount. I have never had a urine infection before from sex.mAny ideas? Thank you!
