Prostatitis is swelling and inflammation of the prostate gland.

You don't need to avoid sex if you have prostatitis. Typically, sex won't worsen prostatitis. But some men who have prostatitis have pain with ejaculation. This can interfere with the enjoyment of sex.

Prostatitis often results from a bacterial infection. It's usually not caused by something that can be passed on to your partner during sex. But in some cases, prostatitis may be caused by a sexually transmitted infection. If you have sores on your genitals or unusual discharge from your penis, avoid sex until you see a health care professional.

Prostatitis and other conditions with similar symptoms have a number of possible causes. Some of them can have serious consequences if they aren't treated. If you have pelvic pain, difficult or painful urination, or painful ejaculation, see a health care professional.
