I'll preface this by saying being overweight or fat definitely makes a person LESS attractive than they would be otherwise, so you don't misunderstand me. But the thing is that it does not make women so unattractive to men that they would want to chase them for sex or relationships. In fact I would go further in saying that every heterosexual man has fantasized about one at least several times in their life.

Instead what men care about is how their friends will see them for dating one or bringing them home. They would be shamed and laughed at by many for doing this
