Hmm. Revisiting this thread, others have have mentioned some breeds that I find quite sexy but didn't think of earlier. Rhodesian Ridgebacks are indeed quite sexy. I have known two intact male Ridgies quite well over the years but didn't have any 'alone time' with either of them.
I love pretty much all retrievers, though one of my faves is the Chesapeake Bay retriever. The big difference with them is they don't love everybody like a Lab or a Golden. If someone broke into your house when you weren't there, a Lab or Golden would show them where all the good stuff is for a few pats. (Yeah, OK, slight exaggeration.) A Chessie would chew the bad guy up just a surely as a GSD or a Dobie would.
I met a Chessie at a dog show some years ago and he was immediately my best buddy. His handler said that was unusual for him as he didn't take to everyone. I saw him again maybe 3 years later and he ran right over and rubbed against my legs like a cat. They have an oily coat that gives them a definite smell which some people don't like. I don't mind it at all!
