Pimples or blisters on the penis may result from localized pressure, trauma, excessive friction, masturbation, or other forms of irritation. If a person engages in unhygienic sexual activities, they may become infected with the herpes virus, leading to blister formation on the penis accompanied by symptoms such as pain and swelling. Additionally, conditions like balanitis or balanoposthitis can also cause blisters on the penis, along with redness and swelling of the foreskin and glans, as well as red patches, cracks, and exudation in the affected area.
