I would post a pic but I don't wanna post my junk up cus I didn't shave . This happens to me once in a blue after sex but my vagina lips become swollen it goes down after a warm shower the next day but this time I jumped straight in to the shower and the water burned I didn't use soap cus I didn't want to make it worse. And let's be real we all pee in the shower at times my urine also stings when it touched my lips down there. What do you think could be the problem the sex wasn't ruff this time I was doing cowgirl I was in control it wasn't him.
