When I first got married, i got multiple bladder infections... and i was always going to the doctors and getting perscribed the medication that takes them away, yet they would always return. I finally had enough and asked the doctor if there was a preventable solution. They said (and I got the same response from different doctors) that what my problem was, was I MUST use the bathroom after intercourse. I thought that diagnoses was pretty mysterious, but took the doctors advice. I havn't had a bladder infection to this day, four years later. I would'nt, but that is just my opinion from past experiecnce.
