Huh? Does it hurt a guy to have sex? You do understand you are asking this question in the “Ask a Slut” feature. I know for a woman it can be painful from experience. If I’m dry and there isn’t any lubricant present that friction during sex is painful. Before my vagina was stretched after all the sex and toys I’ve had up my snatch whenever a larger object or large penis penetrated me there was pain. I could go one but you get the idea. Sometimes there can be pain during sex for a woman so I can only assume there may be times it can be painful for a man. Hubby says dryness during intercourse can be painful for the man too. Of course any infections such as yeast for the woman causes burning during sex and hubby says it burns him too. I hope this helps. Maybe the person to ask is your partner and let him tell you what is or isn’t painful to him.
