There are a number of physical factors as well. Pain is sometimes experienced in the testicular or glans area of the penis immediately after ejaculation. Infections of the prostate, bladder, or seminal vesicles can lead to burning or itching sensations following ejaculation. Men suffering from cystitis may experience intense pain at the moment of ejaculation and is focused at the tip of the penis. Gonorrheal infections are associated with burning or sharp penis pains during ejaculation. Urethritis or prostatitis can make genital stimulation painful or uncomfortable. Anatomic deformities of the penis (retraction of a too-tight foreskin) may also result in pain during sexual act.
