Do you belong to dating sites or sites that specifically cater to those interested in D/s or kink? You can check for kink related events (munches, demos, play parties, etc.) though I think a munch or demo would probably allow you to meet others and interact.
The women you attempt to be submissive toward; how do you know they're dominant? I come across as very dominant, especially at work as that's my job. Outside of work, I'm pretty darn submissive with the right person.
If you're looking for kinky play once in a while, you might want to give a Pro Domme a shot. You would most certainly be shot down if you approach a lifestyle Domme and say "hey, grab your flogger and beat me" as that's not really how it works.
Good luck!!!
