Hello,
The rashes on the penis can be due to balanitis or
contact dermatitis. Avoid the use of chemical cosmetics or soaps, spermicides, cologne or latex condom that are causing you allergy and rashes. Restrict the amount of
carbohydrate and sugar intake to avoid bad odor on retracting the foreskin because sugar in your urine collects under your foreskin where bacteria starts to breed causing rashes and pain. Take care of your hygiene.
Avoid sex for a couple of days to stop recurrence. Your skin is sensitive. Apply a thin layer of
Soframycin ointment on the area affected for relieve. You can take
acetaminophen, one SOS when required to ease pain and discomfort. You should get relieve, if not you may need a course of antibiotics. To stay on the safer side get STD tests done. Get clinically examined by a GP, your treating doctor may recommend
circumcision. You will be treated & managed accordingly.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
