Back before menopause, when my wife and I were a bit more sexually active with each other (we've always been faithful to each other, I know that for a fact), when we did "69", sometimes she would leak a little pee or would have gone to the bathroom beforehand and there would be a little pee left. I have always LOVED my wife's scent, her "natural perfume" as I call it, and the scent of the pee just added to it. I also found myself liking the taste. Yes, this will seem real weird, but it tastes, to me, kind of like microwave buttery popcorn.
In more recent years, since she has gone through menopause, she sometimes leaks a bit more than she used to and, when we have made love, as we still at least occasionally do, it has not bothered me at all, I actually enjoy it. And, while some may go "EWWWW" about that, unless someone has an active infection, urine is actually sterile when it comes out of the body. It is also largely water with a few trace substances such as the famous phermones, urea and the like. And, oh, by the way, MANY cosmetics, some drugs - such as birth control pills of some kinds - salves and the like contain UREA, sooooo, anybody going "EWWWW" has probably had urine in and on you as a cosmetic, aalve and various prescribed drugs. And my wife has always sucked and licked my penis and always swallowed my semen so, although I enjoy it, contact with her urine in and on me is the least I can do in return. If my wife would agree to it, I would get her to pee in my mouth, from time to time, but she just has a problem with that although she knows that I get some in my mouth with I lick her clit and fuck her vagina with my tongue.
