Flint is correct, if you are being the dom and the lady the submissive, we require a second lady be present to supervise because of those safety concerns you mentioned.
We do have the dungeon with a worship chair, human cage, spanking saddle, wall restraints, forced masturbation chair, etc. Also many of us ladies bring our own fetish equipment and toys. We can certainly indulge D/s fantasies here. It will depend on the specific lady as to what exactly she is comfortable with, and I’d wager that if you find a lady and get along well, the trust aspect will grow as you see her more than once and for longer periods of time.
