Hi and welcome to Healthcaremagic. Thank you for your query.
I understand your concerns and I will try to help you as much as I can.
Yes, it is possible to have clogged glands or
fordyce spots and also it may be rash due to
allergy or irritation.
I dont htink this is STD but if there is associated pain,
fever, urethral discharge and recent sexual intercourse thn it may be considered as well.
Second, it may be sign of uroinfection or urinary stones and some other
genital infection but this is less common. In every case, he may need antiallergic and antibiotic ointment so he should see
dermatologist about this. Till thathe should drink plenty of fluids, avoid sexual intercourse and rest.
I hope I have answered you query. If you have any further questions you can contact us in every time.
Kindly regards. Wish you a good health.
