From a distance, your muscular body will probably score you more points, but when you get up close to a woman, it is better to have a nice face I think. But, I think MOST women are more concerned with the person as a WHOLE: personality, overall appearance, intelligence, etc. If you lack in one area, you might make up for it in others so it becomes insignificant. If a woman is attracted to you, your faults are ignored at the same time she is trying to make up logical reasons WHY she likes you.
But since you asked, on the face I have heard women absolutely LOVE nice looking eyes, and lips. They stare into your purty eyes, and then they continually glance at your lips as you talk. The lip look is often when they're thinking more sexually. Women on the forums, tell me how accurate this is.
Tazman, I'm with ya dude, I am a respectable 5'8", but I'll be damned if I can break 130 lbs. Face is like all I got too, I can't lie to myself and say I look like Schwarzenegger in the muscle department, but I'm thankful for my face. I work out some too but what good does it do when you have such a small frame, and a small head on top of that? It might actually make you look worse if you look really out of proportion like that, which is why I said f it.
For a woman, I don't care how good her body looks.... if her face is not hot I don't want her. If she has a great face but mediocre body, she is in a much better position with me. I just like average female bodies: a bit of hourglass shape and average weight and average tits and ass, nothing more. I'm thinking most women are the same way but care even less about your body.
