You've just made me think of something gross. About 30 years ago, a friend had a friend (female) who was the "girlfriend" of a gigantic fat fuck. I mean he could barely walk. I was always curious as to why a reasonably attractive young woman would want to be with such a grotesque piece of shit. So one day I asked my friend about it. She explained to me that the fat fuck was incapable of sex. All the "girlfriend" was required to do was come over to his place a couple of times a week and walk around his apartment naked or in underwear and he would watch and get off on it. He also paid her money for it. Since she didn't have to fuck him or be intimate with him in any way and she wanted to further her studies but couldn't afford it, it was a win win situation for her.
