I'm with Mad Lews and pejanon that physical descriptions are best kept minimal, so the reader can fill in details. My dream guy, for instance, always has short hair. So unless it's crucial to the story that he be shaggy, I would prefer that detail left to my imagination. I feel the same way about descriptions of women, especially when male writers start speculating on dress size, measurements, etc. Way too specific, IMO.

There are a few things that are probably universally attractive--a strong, nice-smelling man is always a good hero. But it might be better to start with the way a woman wants to *feel*, and particularly, the way you want the woman in your story to feel. Strong muscles and soft skin=safe and secure. Gentle hands and an easy smile=relaxed and comfortable. Chiseled body and inscrutable eyes... you get the idea. The words should point toward the guy's character.

Also, I personally like the contrast between men and women. I'm not a particularly delicate woman, and my partner isn't Mr. Universe, but I'm soft enough and he's hard enough that there's a noticable contrast between us. I liked ID's "effortlessly scoops her up" and sheepishone's "strong fingers" wrapping around smaller ones. It's not the specific details, it's the aura.
