I maintain that nothing is really "weird" anymore, though, on account of my already buzzed head, I've gotten quite a few "shaving" fetishizers who want to literally shave my head bald to the scalp, and, I assume buff and shine it, too.  

It'd be an interesting look but I've never taken them up. I need my peach fuzz.

I'm more often surprised by non-event requests spoken in hushed tones.  Granted, my guys are all word of mouth at this point, so no experienced punters, but I get a lot of:

"Ohhhh... Could you... If you don't mind... Do you have a little black dress you could wear?  And heels?"
(Ummm sure.... Isn't that the default uniform...)

"I know it's weird, but could we just talk a little while first?"
(That was the plan...)

Liking pedicures, natural make-up, and plenty more graphic but totally regular things.  It's pretty obvious that guys NEVER talk to each other about their actual preferences.

For him and nurse out fit for me

between a gentleman who wanted me to wear sky high heels and dig my heel into his nuts, and the one who wanted to bring a disabled persons potty chair with him and he would lay under me while I take a big dump on his face.  I turned down both of them because neither appealed.

The most interesting I have never been asked to do again is also a toss up.  I was once asked to wrestle with a guest and whoever won each round got to pick what the other would do to them(it was fun), another time I was asked to dress up like a Robert Palmer girl full make up with pale face and all(most interesting thing I have been able to accommodate).  Both were alot of fun!
