Masturbation can cause penile ulcers.
Although masturbation does not normally cause penile ulcers, when it is too violent and causes damage to the penis, if the injury is not treated promptly, it can cause infection and inflammation, which can lead to the development of penile ulcers. To avoid penile ulcers caused by masturbation, it is important to develop good habits, keep the penis clean and dry, avoid excess sexual stimulation and reduce or eliminate masturbation.
