So, about me and what I'm maybe here for ... My wife and me started experimenting with feederism, master/slave, open marriage, chastity some 20 years ago.
We thought it'd be an interesting journey but it got out of hand. We tried to push each other over the edge, at first in a playful way, then out of vengeance, then we dropped the concept of "consent" altogether; and eventually, we got so mentally conditioned to it we were basically ruining ourselves at the slightest trigger.
I needed more exciting things to be able to climax, whilst simultaneously perceiving every climax as proof that I wasn't sabotaged enough. I'll happily talk about the whole experience but to make a long story short: eventually we divorced.
Yet it still wasn't enough for me. Both to repent/punish myself for what I'd done, and because self-sabotage was the only path left to me, I challenged myself to finish the job and ruin myself so completely and definitively I'd be unhappy with the result for the rest of my life; yet unable to change my mind or ever resolve the problem.
I am unsure if anyone can relate, but perhaps some internet goddess might get a good chuckle out of dropping the axe. No safe word. No limit.

I don't believe in limits. I love breaking them, as much as I love for others to break mine. A "limit" is nothing but a target to be surpassed.
