I don't mind sending deposits for a session. The way I see it there are only two reasons why a sub would be hesitant to put down a deposit.

1) They are not sure they will (be able to) follow through.
2) The Domme has little to no reputation and they are concerned that they might be scammed.

When deciding to send out a session request I first ask myself if either of these are issues. If they are I pause and reevaluate.

That being said, I do appreciate when a Domme who previously asked for deposits, no longer requires them from me. It does feel good to be trusted by someone you put so much trust in.
