Whores don't care about a fat dick. They care about a fat wallet.
Yes, what a guy does would make a difference, but mostly because it could impact his availability.
Two of my friends were married to guys that worked on film crews (the movie business is pretty big here in NM). Those guys would be gone for weeks at a time and some of the stuff that occurs on film locations is not exactly family friendly. One couple got divorced and the other couple had a "me or your job" moment. He chose her.
That kind of thing wouldn't cut it for me. My husband is a chef, but he doesn't cook professionally much. He teaches. If he were at work five or six nights a week until midnight, I'd never see him and our relationship just wouldn't work.
That being said, I don't think it matters so much where you work as how you work. If you resentfully drag your ass off to work every day and come back feeling crappy, having spent the whole day shirking and being miserable, I don't want to see you, even if you're pulling down big money. If you go to work at Wal-Mart and do a good job and have some self-respect, that's better for me.
Money isn't important to all women. My ex had money, family money, and I think it ruined him as a human being. I don't care what kind of car you drive but I do care if you drive like an asshole and take up two parking spaces.
