Soak in a bath with nice smelling bath bombs.
Baby powder them.
Dont let a female near them if they smell-it wont impress her and she WONT be back for more.
If you scratch them make sure your hands are clean.
Wash your hands after you scratch them.
Nice smelling balls are the way to go. Cheers.
Scratch 'n Sniff Balls. I don't think there's a market for that.
Maybe you have a fungal infection, get the stuff from the drug store to treat it with. And like jules76 said wear cotton and air them out so you won't be as likely to get it again. While you are at it treat your feet with the treatment also because it is the same thing as athlete's foot and more than likely you will have it in both places. Good luck with your newly fresh smelling ones !!
How do you manage to smell them? Contortionist? :-) hehehe!
In addition to the other answers meteorite & Jude76 gave I would also shave if you dont already.
Also try wearing cotton boxers, to let more air circulate down there.
See a Doctor and then read literature on STDs
I'm very grossed out...
Ask a doctor.
Don't scratch them.
