Some men cannot reach orgasm at all, at least not with a partner. Retrograde ejaculation is the least common of the ejaculation problems. It causes semen to back into the bladder during orgasm instead of exiting by way of the penis. The semen is then later flushed out when you urinate. Retrograde ejaculation can be caused by diabetes, nerve damage, various medications, and surgery that disturbs the sphincter muscle.
