okay so this might sound gross but I had sex this past weekend , and when he went in and starting going it started hurting like a bitch , and then my vagina like blew up like a puffer fish ( sorry tmi) but then we stopped and ended up doing it more the next day, and it still hurt and did the same thing. and after I peed it started burning a little and now it's starting to get a little itchy .. any suggestions on what it is or what I should do?
