I woke up to an enlarged bump on my shaft/scrotum area the morning after sex. That morning it was enlarged and has gone down in size the past few days. Just seeing if there is any input on what it might be. It is not painful and not very much raised at this point. Please any help would be much appreciated.
Unlikely to be connected with the sex, more like if you shave the area it is linked to irritation, something that occurred during the sex could have irritated it further.
if the sex was unprotected, go get tested if you are unsure
