I'll start. I'm over 40, male, Dom with over 10 years of experience. I would never call myself experienced, since I believe ownership kink is more of an art, with much skill involved, but artist can be skilled, talented, successful, popular but rarely called experienced.
I had long, short and one time relationships. I prefer long ones, they allow to explore person's depth and connect much better than just a hookup, but to each their own. Most of my interactions were online, but with one pet we clicked so well that we've met IRL and spent wonderful few months.
I'm in control fetish, not so much in pain, and my humiliation skills definitely needs improvement. Appreciate advice from those with experience in it, btw.
I do not have a limit list or anything like it, as long as pet as obedient, we can work out limits and schedules, it was never a problem and I had successful relations with over 2 dozen subs. Pretty much only hard requirement always was to report timely with occasional pics.
I use Kik for all my subs interactions. Feel free to ping me for a chat or anything. Same username.
