Well, I am going to jump in and let this be my first post because it is a great thread!
Men:
Criss Angel, hands down, can tie me up any day...I think he flies his MindFREAK flag very high in private.. :-)
And as a second choice (or maybe both at the same time) David Boreanaz..in full on Angel persona of course....
Women:
Mariska Hargitay and Milla Jovovich. They have just the right amount of bad-ass for me......
