In men as in women, there are a number of physical factors that may cause sexual discomfort. 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 intense burning or itching sensations following ejaculation. Gonorrheal infections are sometimes associated with burning or sharp penile pains during ejaculation. Urethritis or prostatitis can make genital stimulation painful or uncomfortable. Anatomic deformities of the penis, such as exist in Peyronie’s disease, may also result in pain during coitus. One cause of painful intercourse is due to the painful retraction of a too-tight foreskin, occurring either during the first attempt at intercourse or subsequent to tightening or scarring following inflammation or local infection (Bancroft 1989). During vigorous intercourse or masturbation, small tears may occur in the frenum of the foreskin and can be very painful.

A rare form of male dyspareunia - postejaculatory pain syndrome - is characterized by persistent and recurring pain in the genital organs during ejaculation or immediately thereafter. The painful sensations are experienced as sharp, stabbing, and/or burning. Although the duration of pain is usually brief, it can persist and be quite intense. Although the immediate cause of psychogenic postejaculatory pain syndrome is the involuntary painful spasm or cramping of certain pain-sensitive muscles in the male genital and reproductive organs, the excruciatingly painful muscle cramps may be attributable to a man’s conflict about ejaculating. Guilt about sexual pleasure or about the paraphiliac nature of the erotic fantasies can lead to pain with orgasm. In other cases, men with liberal sexual attitudes might resent women or be angry at their current sexual partners for unconscious or conscious reasons.
