You crack me up! Your grandmother? Did you REALLY have to go there. Visual...... LOL
I don't know about the tying up part as far as it being ME that's tied up. Maybe I've seen to many movies involving ice piks or something.? I have no problem tying someone else up though. And the blind-fold thing, that's a must!
I'm talkin' "throw down" and "get aggressive" kind of stuff too though.
I think most men like a woman that takes control. Maybe I'm wrong. I know my man has no problem with it. I probably just don't do it often enough. Doesn't mean I don't want to, but I know that proof is in the pudding.
