I hope you get more response this time. (BTW - good to see you here!)
I have noticed many male subs posting introductions, but then they seem to disappear. I have no idea why - thay may be joining in order to access the library chat rooms. I don't visit there so I don't know that for a fact.
Now comes my opinion. I have talked to a couple of Dommes - and they say that often males subs have a very specific script for the Domme to follow. The Dommes said that was incredibly irritating, and they do not want anything to do with that. So maybe some male subs are more into having fantasies fulfilled than actually submitting to another.
