Re: itchy crotch
I wouldn't recommend that you use gold bond for your private parts as it can cause burning and irritation.
You should first figure out what's causing your genitals to itch it could be anything from jock itch, lice, chaffing , STD, to a fungus infection you can try to treat it with over the counter ointments, also cornstarch and talcum powder can help with chaffing if that's the cause of your itch. Also excessive sweating can be another cause which can be prevented with showering frequently.
If it's a fungal infection wearing loose fitting, clean, cotton underwear is recommended along with a fungal medication. But if no ointments helps relieve your itching, you should probably see a doctor. You should check your genitals for any lesions such as rashes or bumps as that can be a sign of an std.
