Kinky is a guy wanting to be tied up and teased. Creepy is being tied up while they beat you and WRONG is tying them up and dragging them with your truck.
It's fun to add a little kink and some role play now and again. Not that I'd want every encounter to be that way as I enjoy good old fashioned sex play a lot. But playing sexetary, naughty school girl and whatnot is hot. Also, using toys for a first time on someone, masturbating for them, or especially watching them masturbate for you...yowser....very exciting!
