A man I used to work with knew about my pee fetish as I confided with him.........I regret it somewhat now. I was later to discover that he had some sort of sex interest in me, despite being a married man himself. I was scared of being blackmailed by him at one stage, I am straight and had no interest in having any sort of bi-sexual relationship with an older male work colleague.
One of my old schoolmates knows also, I regret confiding in him as he finds it repugnant. I keep it VERY private nowadays... :)
