Melior,
I don't imagine the lack of interest reflected on you personally. It's a simple case of supply and demand. There are a lot of male subs out there (and my gut feeling says that the population of male subs is increasing at an increasing rate), but few Dommes.
Maybe a good thread to start, and one that would gain you some attention, would be one that asked whether or not an ever more stressful and complicated world is causing an increase in male subs.
