Experience, no. Thoughts? Seems like he’s trying to occupy a specific kinky niche, looks like domination.
How good he is at occupying that niche, idk, but it’ll also depend on how well you, and he, communicates and negotiates boundaries, fantasies, likes/dislikes… I’m relatively new to hiring. I imagine trying to communicate and negotiate that kind of session, with I imagine D/s tones with someone you haven’t met before, adds another level of difficulty, but I could be wrong.
It depends what you want, how you want to spend the time.
