Fat and skinny are a part of it, I rather look at healthy or sick. Over weight people even though we love them end up with knee and hip problems, heart and other health issues which strain relationships. Inactivity and unfit people can't perform when they need too. It's a big subject really

Yes, if women get fat, men don't like us, but if they get fat we are supposed to like them anyways.. o.O

They are an aspect of every relationship. How large of an aspect is down to the individual judging their partner.

I would help for some, but for me I think her personality is more important

Being physically attracted to your partner really helps!

It is but he only needs to look attractive in your eyes.

That depends....

maybe

Staying healthy and fit makes sense. But people age, that's life. You're not going to look the same way at 45 that you did at 20.

Initially yes because looks are what attract one person to another... however looks become less important as time goes... You can be with the most gorgeous human being that walked the earth. But if they are an ass then those beautiful features fade fast.
