I went to the beach yesterday, and I woke up today with 3, small, red bumps on my penis. I decided to look online for some help, but the only thing I could find was "MRSA," which looks nothing like the bumps I have. I WAS wearing swim trunks with a netting, and the bumps position looks like the "shape" of the netting. Is this just a small thing that should heal soon? Or is something serious?

Well you know when you sit on your feet on some type of fabric and it makes an indent on your feet? Well maybe since the "net" was against you for so long then it must have started to make an indent and then got worse because you didn't take it off. Try a bathing suit that doesn't have a "net" and see what happens. If it gets worse after a whilethen you should see a doctor. I think your fine just take it easy

Good luck!
