I hope you also know that the word "mentor" in the BDSM world really means No contact!!
Sexually speaking.
Also YOU ask to be mentored! A mentor never asks you.
That's a red flag in my opinion.

So what is involved? Is there a verbal or written contract? Is this person vetted? Known in the community?
IMHO there should be no play before boundaries are in place.

This is where eager beavers get really hurt.
Hope this helps!!
