I'm dating a guy who gets erections from sneezing. He has pretty bad allergies and if he has an allergy attack, by about the 5th sneeze, he's starting to get a boner. I've actually seen this happen and was pretty surprised, but he says has no control over it and has to find a way to hide it until the sneezing stops. He said that he is able to stop a sneezing fit when it happens at work, so he won't be embarassed, but that's the only time he tries to stop it from happening. I know this sounds weird, but I need to know if this guy is for real about this. I was reading that guys can get erections from a full bladder, but what about this sneezing thing? Has anyone ever had this happen to them or know anyone who this happens to?
