I wouldn't really recommend any of the above. I've never been particularly impressed by Kezia Noble, strikes me as a bit of a money grabber. Then again I wouldn't be surprised if she'd fucked more girls than the other two, and she basically just fucks guys.

Tyler and Alex from RSD are worth a listen. Other RSD people too maybe if you like. Just take it with a pinch of salt and resist the urge to drive round in a rape van shoving japanese womens faces into your crotch.

Tbh you don't need an awful lot. You can hoard information all you want but the only real way to learn is to get out and do it for yourself.
