Hello,
You are suffering from rashes on the shaft of the penis. It gets irritated and is failing to heal due to friction rub from your pants. It is burning on
masturbation and is causing you discomfort. Your symptoms may be indicative of allergy due to latex(condom), drug rash,
contact dermatitis, sexually transmitted diseases,
psoriasis, syphilis, herpes, etc. You are suggested to take care of your hygiene, wear loose fitting cotton clothes, avoid multiple partners and also any sexual activity till you heal.
You can apply ointment
Soframycin for relieve on the affected part. You can also apply ointment acyclovir, it is effective. You are suggested to get clinically examined by a
urologist. Get STD tests done. If found positive you will be treated with antibiotics and antivirals. Stay away from addictions if any, smoking, drugs, alcohol, etc., for the best efficacy of the medicines.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
