Hello all, this is my first post here but I figured it a good place to start. :)
my first girlfriend ever from high school, who I was with for 5 years, knows. She sensed about half way through our relationship that I wasn't totally satisfied and cornered me into asking what's wrong. I was really stressed by the whole thing out of fear that she'd be disgusted, and spent likely a half hour dancing around it, until I finally laid all my cards on the table. To my surprise, she was very accepting and it was probably one of the most positive experiences I could've ever asked for. That being said, she was also not into it, and while she'd indulge and let me experiment, she'd also lose patience sometimes. I am always thankful that she was so accepting, but wish it could've been more. We are actually still friends to this day.
Other than her, I only had one other person who I told, albeit with much less stress. It was actually pretty early on, she was a friend that became a little bit more for a while, then nothing. She was also not super into it, but she liked how much it turned me on and in hat respect got off to it, which I liked.
I've actually stopped trying to make vanilla relationships work for the most part. I was with someone for a while who was sexually amazing, by far the best I've ever had, but she would get real grossed out in non sexual pee situations and I could tell it wouldn't work out if I told her. I want to find someone I can share this kink with, which I suppose is an uphill battle, but I'm hopeful. :)
