Have you experienced dry orgasms or retrograde ejaculations?

Some men can experience retrograde ejaculation, or "dry orgasms," when semen travels backwards into the bladder instead of being expelled. The illness can be congenital, or caused by medications, diabetes, or damage to nerves and muscles that control the opening of the bladder. It isn't harmful, but it can cause male infertility. You'd think that any orgasm would be good. You'd be wrong.
