What is the first thing in women that atttracts men the most ?

I think the physical look is the first thing that magnetize men in women. But this kind of attraction is temporary and will soon fade as it takes a good character and an intellectual brain to make men stay with women. Normally beautiful women are unfaithful and this is one of the downside of physical attraction. Too many men attracted to a pretty face can be a real challenge to all men.

I guess it's a woman's appearance usually. Good shape, a smile, a blink.
