My girlfriend was always getting UTI's with her boyfriend. The doctor told her to drink cranberry juice - it wasn't a cure all to be all. Then she disclosed to her doctor that her husband has really large genitalia and her doctor instructed she take 1 cranberry pill everytime before having sex. She does this religiously and now they are married 6 years with a little girl and no more UTIs....but she never skips her cranberry pill - she keeps them bedside. If you decide to try this route let me know and I can ask her if there is a specific brand / dosage she recommends.
