I agree... eyes are the first thing I notice, then his smile and then his teeth... I don't expect perfect teeth, but I do expect it to be obvious that he brushes them regularly. OMGosh... this one guy I met... nassstyyyy!!!!
After that, I notice a man's hands. I like big hands.
I agree with MrGW....... the face... eyes first because they tell so much and then the facial expressions unless u are a very good liar the true feelings can always be found in the face....... I love beautiful eyes... color not important....... smiles, me
"What part of the body"? Well, if we're talking about a woman's body..............well everyone knows what part(s) are most interesting to me. Seriously though, I've always found that a lot can be surmised by looking at a persons face. Is their face all "scrunched-up", is it quite serious, does it seem worn as though used to thinking and hard work, perhaps it might be a serious one with just a twinkle in the eyes? Also, you must see the way a person carries themselves. Do they just trudge along, do they have a sure and determined gait? This subject, body language, can be a very interesting one. Did I get a bit off subject? Sorry
