Noticed a recurrent macular rash on my glans penis after intercourse. No pustules, no drainage, causes pruritis. Dermatologist or urologist?

Derm. See a dermatologist or your primary care physician first.
Either. This may be sensitivity to vagninits, feminine hygiene product. The use of a condom mmsy prevent rash. If there are no signs of infection topical Hydrocortisone and non sedating antihistamine to prefer rash.
