I am 37, 156ibs, and 5'7. I sometimes have an odor of pee in my underwear and my husband says that it is the same during sex when he tries to do oral. It is definately unattractive. I have been checked off and on for urinary infection and it has always come back negative. I had a son two years ago and this has been an issue ever since, Is there anything I can do to stay fresh and change the smell/taste in that area?
