Hey NeverDie, it's often said that fat chicks are better at sex because of how eager they are to please. Also, being able to work your unsatisfying member between her body rolls in a manner which makes her orgasms real would surely feel gratifying.
Also, if somebody loves a person enough and knows what their preferences are, wouldn't they want to try to attain a better figure? You know, so that they'd have something with which they can wow their partner? It's obviously not essential at all, but that sort of thing is nice as a whole. Even if it's something as simple as shaving oneself, that alone is a nice treat. Honestly, Jarby as a fuzzy, cuddly thing would still be brilliant, but hairless is just aahhhhnnnnnng
Really, tell this guy that if he cares that much about his figure, he should get off his backside and improve it. I take a lot of pleasure in working out when I can be bothered and all of this walking to, from and around my place of study (twenty minutes to and from the bus stop in town up and down a load of slopes; not to mention walking for a bit in order to find something to eat) is having a profound effect on my legs and ass. I think so, anyway.
DEEDIT: Okay, this reminds me of my pet hate, which regards people who complain about something but can't be bothered to do anything about it. failboat, if your friend is miserable about his figure while he can do something about it, then he deserves to be miserable. If there's nothing that you can tell him that will make him be happy with his figure or improve it, then he's a lost cause and you shouldn't give him the attention. Perhaps he could work himself up enough to sort it out himself.
