Mistress Ayn,
While i think about kink all the time, it's been years since a real time. i did participate in on-line Domination a couple years ago and continue to be in touch with that Mistress, who has retired.
Health issues keep me from participating RT.
Before the health issues, finances were a limitation. And sometimes demands on my time. my first session was in the late 1970s and i have had more than a dozen at least. However, they were often spaced apart in time.
Another limiting factor, there weren't many Mistresses around my area/or they were difficult to locate in pre-Internet days.
