Amethyst: there's NO reason to feel second rate. The pictures of women on the titty board here are just that, pictures. they're air-brushed, edited to make them look the way they do. Your not looking like them doesn't mean a thing, other than the fact that you're human, and not an image on a page.
Replying on the titty board is a way of saying "thanks for putting the effort into sharing these pics with me." it does NOT mean that the poster thinks that woman is the most beautiful woman in the world, nor does it mean that he would chose to have a real-world relationship with her.
He most likely doesn't SETTLE for you, at all. he chose you, out of all the women in the world, because there was something he liked. I don't know what it was, but I bet if you asked him, he'd tell you.

AND, I bet it has nothing at all to do with your looks.
You're not being a baby, at all, you just need to step back and think about it logically, instead of feeling second-rate. He looks at porn, because it's pretty. he loves YOU, because you're special. see the difference?
