I have learned from pro-domme work that most older guys (50+) (i.e. the only ones who can actually afford to fucking pay) really just want to be cuffed a spanked. They don't have the crazy sexual hang-ups and special requests that young guys do. Young guys want to draw up a 50-step fantasy and demand each one is followed perfectly, and if not, their whole experience is ruined.
I will take an older client only from now on. More mature. Pay correct amount and on time. And they are simple: Cuff and spank.
