There are two aspects of this that women will never understand, and you can find both in this thread.
A. Women think this is a moral issue, as if good upbringing will cause a guy to not need to be attracted to his wife.
B. Women have a much more holistic view of “looks”, and count all sorts of odd things in the mix, and especially diminish the significance of weight. (look Sac, he’s talking about weight again.)
