A wound/fissure on penile skin persisting for months is not considered normal and should be examined by a dermatologist or urologist in person. From the photos, possibilities include chronic frictional fissure, fungal/yeast infection, dermatitis/eczema, balanitis, or less commonly a chronic inflammatory skin condition.
Keep the area clean and dry, avoid harsh soaps, avoid excessive friction/masturbation temporarily, use loose cotton underwear, and do not apply random steroid/combination creams without examination.
You may need evaluation for:
* Fungal or bacterial infection
*
Diabetes/
sugar testing
* STI screening if sexually active
* Sometimes biopsy only if lesion looks suspicious or non-healing for long duration
Since it has persisted this long, please do not rely only on home treatment. An in-person dermatology/urology consultation is recommended for proper diagnosis and targeted treatment.
