Hello,
It can be because of any allergic contact dermatitis to the condom, lubricant, the cosmetics or soap or detergent that you are using. If it appears as a red itchy rash then fungal infection needs to be ruled out.
He can apply an anti-itch cream or lotion to the affected area. Oral antihistamine, such as Benadryl can also be used. He should take a comfortably cool bath and wear smooth-textured cotton socks. You should choose mild soaps without dyes or perfumes and use a mild, unscented laundry detergent when washing clothes, towels and bedding.
Please take a second opinion from a dermatologist if the symptoms persist. Topical and oral steroids may be needed.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
