Hello

I totally agree with flying66, 24/7 and true lifestyle persons are extremely rare.
I have lived with one such, but they really are one in a million.

Before that I spend 12 years with one of the bedroom variety.
And our story have somewhat more to do with the thread, because when we met, either of us had no idea about the other persons inclination.
It was something we discovered over the course of our two years, I quietly introduced this as a variety for erotic play at first.
And I use her habit of pinching me at erotic times as one 'excuse' for tying her up. Now in hindsight it is all obvious for everyone on a forum like this one that it was her way of trying to trigger me to handling her roughly.
Anyhow it took a full two years before we finally got it out in the open.

And that is my reply to the OP, if you see any such signals, or other submissive and/ or playful tendencies feel free to proceed. But else you might still have the option for some roleplay and a little light bondage as a variation. Nothing impossible even with one basically vanilla person.
