My darling husband tried to achieve an erection last night as an experiment (he says). I reminded him that he still had a catheter in (as if he forgot), and that his discharge papers clearly stated NO SEXUAL ACTIVITY. To make a long story short, he actually had some small results. BUT..... during this "experiment", I noticed a weird localized swelling on the underside of his penis. Almost like a fluid filled sack (about the size of a quarter in diameter. He says it didn't hurt. I will definitely be telling the doctor on him on Tuesday, but until then, does anyone have any clues as to what this might be?
