Other than her face, it would be her stomach and navel. A firm flat belly usually means she is healthy and takes care of herself (as opposed to fat, chubby, or the other extreme anorexic). I find the belly very sexy with the navel the center of my attention. A perfect vertical oriented oval innie, is like the cherry on an ice cream sundae! Perfect for teasing with a finger, and stimulating with kisses and tongue probing.
I do the exact same. I tend bar at outdoor concerts May thru August. The view can be amazing. Nothing hotter then a woman who goes braless.
Eyes, I love seductive eyes, followed by full luscious lips, then breasts (real are the best), then nice shapely legs, followed by a nicely rounded ass! I don't like skinny, I don't like super fat. However, I get hard as a bat for a lady with curves that also looks to be fit!
I tend to look at the collar bone area. It's really sexy on both guys and girls. With guys it outlines the chest and really accents it nicely. With girls it's just a beautiful natural slope to the breasts. I look at a nice ass and other things, but the neck area is really at the top of my list.
Legs. I live in an area where ladies wear short shorts most of the year, and it makes trips to the grocery store a real pleasure.
Not the first thing I look at exactly, but the first thing I notice is the confidence, swagger, poise...the way she moves. Is she sexy. I don't care what a girl looks like, if she lacks all that, then I'm not impressed.
My husband is tall, works out a lot, and his eyes are just amazingly expressive. I also love beards. I've always liked this total combination.
Hair, as in the hair on her head, mainly because I just find nice hairstyles attractive. But "nice" can mean a lot of different things for me. Punky short, spiky hair, long hair, medium length hair, are all nice in their own ways.
