Dude, us, trannies who want our dicks sucked, don't particularly care if as long as you're good at it and don't expect some weird shit like litres of cum that you see in porno when in reality most of us come dry unless we jump through the hoops that may or may not be sabotaging our transition.
You're worrying about the wrong things, what you should be worried about is your behaviour in general, if you act like a spineless doormat, it's a massive turn off, most of us want men who act like men, aside from those trannies who are into fucking twinks, the power dynamic there is its own thing.
