WHats hot and whats not is a matter of personal opinion. But when you say "a porn girls job is to fuck and look good, yet so many look like shit....instead of looking like a drug addicted fat porn whore?"
I'm sorry to break it to you but more than half the girls in this industry ARE DRUG ADDICTED and/OR FAT PORN WHORES!!! And you're right... that's not hot/attractive, at least the drug addicting part. I've come across many heavy set women who are fucking hot and pull it off nicely. But yet again thats a matter of personal opinion.
