my husband constantly looks at other woman's FB sexy photos and is look at porn, why?

[WOLOLO Monk]

Go look at yourself in the mirror, you'll realize the obvious answer.
Compare yourself with a hot porn star or a hot facebook women, you'll realize the obvious answer.
Go stand on a weight scale, you'll realize the obvious answer.
Lift your arms and look at the dangling muscles, you'll realize the obvious answer.
Look at your thighs, belly, baby fat, you'll realize the obvious answer.
