Can I suggest you refine your search methods?
What you are looking for here borders into the area of Tantra it might even actually be fully into that category if you ask some people?
My point is, talk to Jules first. She loves stuff like this, had me bent, folded and impaled to a point of erotic stretchology second to none. I wish I could stretch with her for 1/2 hour every morning.

After that, research tantra providers, there are good one and not as good ones. Some that are legit cool, sexy tantric minded people and there are posers, like the BDSM community, or any other community for that matter.
I don’t know if Yuliya would provide this but I’m pretty sure it’s up her ally. She’s also in the LL massage section. Can’t hurt to ask?
