Red pimples on glans penis after erection

The appearance of red papules after glans erection may be related to factors such as balanitis, allergic reactions, pearly rash, condyloma acuminata, or fixed drug eruption. It is recommended to seek medical treatment promptly for a clear diagnosis and avoid self-treatment.

1. Balanitis

Balanitis is mostly caused by bacterial or fungal infection and manifests as glans erythema, papules with itching or discharge. Clotrimazole cream can be used to treat fungal infections as directed by your doctor, and mupirocin ointment can be used for bacterial infections. It is necessary to keep the perineum clean and dry every day and avoid scratching.

2. Allergic reaction

Contact with allergenic substances such as condoms and detergents may cause local allergic dermatitis, with red papules and burning sensation. Suspected allergens need to be stopped immediately, rinse with water and apply hydrocortisone butyrate cream externally to relieve symptoms. Severe allergies require oral loratadine tablets.

3. Pearl rash

Pearly rash is a benign physiological variation, manifesting as small pearly papules neatly arranged in the coronal groove of the glans penis, and does not require special treatment. If it affects the appearance, it can be removed by laser, but it needs to be differentiated from genital warts. It is recommended to be diagnosed by a dermatologist.

4. Genital warts

Sexually transmitted diseases caused by human papillomavirus infection, the papules are cauliflower-shaped and may increase in size. After diagnosis, cryotherapy can be used to remove the warts, or topical imiquimod cream can be used. Other sexually transmitted diseases need to be checked at the same time, and sexual partners should be checked together.

5. Fixed drug eruption

After taking sulfonamides or antipyretic analgesics, well-defined erythematous papules may appear on the glans, which can be relieved by taking oral loratadine tablets after stopping the drug. Re-use of similar drugs will cause recurrence in situ. Allergenic drugs need to be permanently disabled and allergy history recorded.

Breathable cotton underwear should be chosen for daily use to avoid local friction and irritation. Just use warm water when cleaning, no need to use excessive detergent. If a rash or ulcer persists after erection, or is accompanied by painful urination, you must see a urologist or dermatologist within 24 hours. Sexual intercourse is prohibited during treatment, and partners who have abnormal symptoms need to be checked simultaneously.
