Some of us women are naturally prone to urinary tract and bladder infections (myself included). One sure-fire way to prevent ANY future problems is to start taking Cranberry Pills. You can get them at any drugstore or pharmacy counter. Make sure it's pure cranberry - no sugars added (sugars are what bacteria feed on).

Since I started taking them, I haven't had one bladder or urinary tract infection, no matter how big the guys I'm doing are. But girls, if the guy(s) did right by you then you'll have no choice but to pee after sex - lol. I always know when my body has been well and truly fucked (and satisfied): I HAVE to pee after the sex - lol.
