lol, I'm completely oblivious to men checking me out but S. always points it out to me with a big grin on his face...he loves it and will ham it up. Once we were walking around DC and he saw a group of guys staring...so when we passed them he reached down and grabbed a handful of ass. I'm the same way with him...I get a kick out of watching girls/women fawn over him. He'd probably spit fire if any of them laid a hand on me, but that's another matter. There's a difference between being territorial and jealous.
Miplank, relish in the fact that you married a woman who gets checked out. She's yours and while they get to look, you're the only one who gets to touch.
As far as the whole thread...there's a million other things I want to respond to, but I don't have the time for it...but I'll say that almost every older couple I know who have been together for years and are actually happy have both - butterflies/passion, and actual real-life compatibility and friendship.
