I'd do so protected. I did, but the friction will cause it to act up. I used lotriman and I was proscribed nystatin
Having had balantis your pictures and discription do look like what I had. Im not a doctor so take it for what it's worth. Treatment was difficult. Keep the area dry, moping up all urine after urination, wear loose fitting boxers, apply anti fungal cream daily, and keep the area clean. Avoid alchohol. It took me 3-4 months to get rid of it. Friction will often bring it back when you think its gone
