Hello, rjt.
And welcome.
There's an element of trust required in any serious relationship. The world is filled with trolls and poseurs and folks who I wouldn't trust to butter bread without supervision. So I suppose, if I were hoping to connect with a sub, I'd work on building their trust in me. Perhaps learn a bit more about D/s relationships? Perhaps spend a little time reaching out to people? Fun and games is one place to get known. Chat is cool when it's up. You might simply write a cheerful line or two - as a private message or visitor message - to subs who take the time to introduce themselves.
For what that's worth,
S.
