Whatever floats your boat!
But that doesn’t mean what floats your boat should/would float mine.
The primary consideration in deciding what I want to do with a person (if anything) is going to be in-person chemistry. That means I don’t do online. At all. Trust me – many have tried. All have failed.
If I don’t feel a certain level of chemistry nothing is going to happen.
I am a sadist and I want my hands on you. I’m also very into a specific feminist sort of approach to my D/s interests that requires you be in person, in public with me. That does not necessarily mean public as in BDSM parties. But it definitely means out and about in public vanilla spaces.
Being in person (IRL) is a hard requirement for me. I expect that you are willing to date me, in public, while we communicate and negotiate all the rest.
There are many reasons people only want online and they are just as legitimate as mine for requiring IRL. Neither is any more or less valid of a way of expressing our desires and having our needs met.
