I had sex the other night with a guy who said he finished twice during the same sex "session". We never changed condoms because I didn't know he had already finished. He didn't get real limp or anything so I'm not even sure that he did cum twice, even though he said he did. It has been 2 days and now my vagina is a little itchy. This has never happened to me before so I'm just not sure what to do think.
