What causes rashes around the private parts?

what causes rashes around the penis?

There are quite a few options here.

1. Jock itch...a fungus that creates an itching sensation and redness around the testes and penis. This is something that you develop on your own, especially in warm climates or if you exercise a lot.

2. STDs. It could be a number of sexual transmitted diseases, including crabs, clamydia or gonnorhea. If you have had sex recently (especially without a condom), check for small bugs in your pubic hair. If you see them, it's crabs and you can buy a treatment for them at the store. If you don't, you need to see a doctor to get tested and probably to get antibiotics.

If you have not had sex recently, I suggest getting an over the counter fungal treatment to see if it clears up.

Probably a STD...should get it checked out. If you are athletic, sweat can cause a heat rash...but probably should be checked out.

Heat and friction; sometimes yeast infections. See a doctor!
