Both of mine will smell like urine if I don't give them a sanitary trim, so you're definitely not alone.  Finnigan used to pee all over the fur on his right side since he lifts his leg on the left and Gwenndilyn peed all over the sides of both legs.  I clip the hair on the inside of both of her legs and also now leave a longer pee string on both to help direct the urine down and away from them.
