What is a woman's favorite physical attribute on a guy?

OOOOOOOOOOOOOOO I love a guy with nice arms and they don't have to be all buff, in fact, I'm not into the who huge ass arms, I'm just talking about nice arms to hold you in.,

my favorite part on a guy isn't on here ;]
hehe.
but if I had to choose
then its a tie between a good smile/face
and the upper body area

haha I like guys who have nice arms and a really nice chest (including abs). but first I usually notice his smile and how he acts around others.

Muscular chest and arms, along with a good smile ; )

A nice smile is a good start, but then I like to see how they interact with people, you know rude, kind etc. Will give you a good idea about how he really is.

For my favorite physical aspect I'd have to say a guy's face, you know if its warm and loving or deep and thoughtful or harsh and rugged! (all are good BTW)

but what I really look at initially if a guy catches my attention is the way he interacts with other people, you know the way he behaves with friends, parents, siblings and other women. From this you can grasp a hint to his personality, if he's respectful, trustworthy, kind!

just my thoughts!

it depends chest and biceps. I prefer my guys to have pecks lol
