After intercourse, then 2 bouts of aggressive masturbation, my penis became swollen & itchy. That has been 1 1/2 days ago. At 1st the swelling seemed to subside, but this morning it was back , large swelling below penis. Itching not too bad now but head itched during the night. Will this subside on it's own ?Any creams that may help, should I see a urologist. P.S. am over 70 years old
