First off let me say that I am circumcised. After a rough session of masturbation my penis is swollen on the left side looking down at it. There is also a very tight vein or vessel just under the rim of my penis head. This swelling has occurred once or twice before after long masturbation sessions. But the swelling has gone down in a day. This time it has been nearly a week and I do not see any much improvement. What do you think is going on? Is there a home remedy to help the swelling go down? It’s not real bad but it is noticeable. Thanks.
