I think you have a really wrong idea about what BDSM actually is. If you’re thinking of a dominatrix, you’re probably thinking of the prime time police procedural version who ties up stock brokers, gangsters, and other psychopaths who lack an internal dialog. They aren’t dominating these broken men, they’re being the missing conscience and it’s not the norm for either doms or subs. A dominatrix isn’t there to control her subs, either sexually / physically or psychologically. Quite the opposite: she’s there to break control, to force the sub to release his self imposed constraints by refusing to acknowledge them.
I’m not saying you should visit a BDSM dungeon, but you could certainly benefit from being released from your various psycho-sexual tics. Of course you don’t want to give up that control, even as it’s throttling your chances at meaningful relationships romantic or platonic.
