My dominatrix friend told me that similarly, men share these sorts of thing with them for the same reasons. When I used to hang out at the transsexual bar Divas in San Francisco (now closed), guys I flirted with and hooked up with for fun, also shared much they shared with few others (and they didn’t share with their wives / gfs). Our relationship was simple - I didn’t expect anything from them, or judge them, and being trans I understood and respected them. I enjoyed the chatting as much as the attention and sex. And I loved making them happy. It was good for both of us. I felt like I was doing something more important then my various jobs - tech person, lobbyist, manager, etc.
