Dang I don't see it as kink shame just sad shit. Sex shouldn't be a transactional coin.

I don't know, from my limited view into the kink community if this was a sub/dom setup he wouldn't need the incentive, the subs I know of in the lifestyle not just the bedroom are legitimately dedicated to their dom counterpart and would do their damndest to keep on top of their duties, not have to be coerced into doing them by a tacky chart

I'm no expert though, I just hang out in a sub focused discord
