How likely is it for you to be passing a urinary infection to your spouse?

Coitus assoc UTI: Infections can be transmitted through intercourse since there is mechanical trauma in a non sterile area. This may be more common w/uncircumcised males har boring bacteria. Bacteria travel by 'brownian movement' up the urethra (urine outlet). It is not uncommon for women to have 'honey moon' cystitis after sex. In those w/ frequent recurrences, your doc may prescribe 'prophylactic antibiotics'.
