19 Things Men Are Most Embarrassed About Their Bodies

Jock Itch

You don't have to be a pro athlete to get jock itch. This fungal infection spreads easily at your local gym -- or from another part of your own body. Hands, towels, and stepping into underwear are common culprits. The symptoms include a patchy rash on the groin or inner thighs, along with the telltale itching. It's treated with nonprescription antifungal creams. Keeping the area dry and avoiding tight clothing helps to avoid a repeat engagement.
