I've been having a lot of itching around my penis and testes lately. Scratching gives me temporary relief, but then it starts itching again. I've tried using Candid lotion, but it hasn't helped at all. I'm really consistent about bathing every day and even use cooling powders, yet the itchiness persists. It's pretty embarrassing because I can't stop myself from scratching in public sometimes. Also, there are visible red scratch marks between my penis and upper thighs. Can you help me figure out what might be going on and what I should do?
