Without examination confirming a diagnosis is very tough but the various possibilities are contact dermatitis,sweat dermatitis,eczema,psoriasis and Lichen sclerosis and balanitis xerotica obliterans.It doesn’t sound like herpes.
Eczema is a form of chronic dermatitis (rash) and can cause dryness of the skin and rashes.Allergic reaction is one of the important causes of eczema. Lichen sclerosis appears as white,dry plaques on the glans, foreskin or shaft of the penis.Balanitis xerotica is a severe form of lichen sclerosis.Psoraisis can also cause dry ,itchy skin rashes.
In my opinion a clinical examination by a dermatologist will help in confirming a diagnosis as treatment depends on the same.Pls get it done.
Hope it helps.Take care and pls do keep me posted on how you are doing and what the dermatologist says.Kind regards.
thank you for the info.........
