If boyfriend has prostatitis, do i need to be checked for vaginitis?

Prostatitis & STDs?: The best answer is yes. Prostatitis can be associated with some germs that are sexually transmitted including both gardnerella vaginalis and trichomonas. The other concern is that if one sexually transmitted germ is present, there may be another. It never hurts to be safe and get checked.

If you're concerned: If the underlying bacteria is chlamydia or gonorrhea it could be sexually transmitted. Safer sexual practices using condoms is always the best option for sexually active people to protect themselves and others. If concerned, get tested, even if you are asymptomatic. Routine followup with your pcp or gynecologist is likely a good idea.
