I seem to somehow have missed this post, but I guess it’s not too late, and offer my response now.
I’ve always enjoyed submissive women and a bit of bondage, but never really looked upon that as much of a kink. It’s certainly not something I seek out with every punt!
I’ve seen several SPs over the years who overtly offer a submissive service, whether it be just restraint, or sensory deprivation, use of nipple clamps, controlled orgasm etc. I’ve tried spanking and the application of more severe corporal punishment, but applying it doesn’t do a lot for me (although it’s pretty erotic to watch it being done.)
The best experiences I’ve had have been with SPs who, once I’ve got to know them, have allowed me to tie them and more, even though it’s not a declared ‘like.’
With one such SP I have myself switched and submitted to domination by her from time to time, and allowed her to use ‘toys’ on me, including hot wax, a TENS machine, a urethral probe, and even a (very small!) strap-on. I also submitted to receiving water sports from her, which was actually incredibly erotic. It was carried out in the open and she’d gone to great lengths to ensure that her urine was completely flavourless. Unfortunately, I no longer see her. It was always a bit of a journey to get there, and since covid I haven't regained the will to travel that far, but this post has revived my interest!
