Probably one of the first things would be to take a nice warm shower and get to know all those new and different parts.

Would not even try to learn to walk in high heels. They're sexy but look dangerous to me.

Then, assuming my wife and I had done role reversals, I'd I think I would probably try all the things I've wanted my wife to do for me.

Then, I'd have her (temporarily him) take me out to dinner where I'd tease her unmercifully under the table.

Could be fun for a day.
