I didn't ask anyone for advice. I only responded to this thread because I didn't like what was being said to the OP.
The fact of the matter is, you can share your anecdotes and I can share mine, but I think it is irresponsible to tell someone who is frustrated and feels they are never going to meet someone that "what they are doing wrong" is something that is inherently a part of who they are. So what if the OP can't lose those last few lbs because that's his natural body or because the things he'd have to do to get to that ideal are just not realistic to his lifestyle? Should he believe he's never going to find love or sex ever again?
I'm sorry, but as a bigger person who is OK with who I am and has no desire to starve myself to look like a frat bro or a twink, I think it is irresponsible to advise someone that they probably aren't attracting guys because they are overweight JUST because they said they wanted to lose a few pounds and are concerned that might be it. It is PATENTLY UNTRUE that all guys on Craigslist are looking for someone with a ripped body. I see guys on CL regularly who are looking for bears, cubs, chubs, husky guys, stocky guys, etc. The whole point of these sites is to find something you like and honing right in on the OPs weight and saying that's probably what is causing him problems is IRRESPONSIBLE and INSULTING. I'm not sure why you don't get that. It is like telling someone who is unpopular, who you know nothing about, that the reason they are unpopular is because they are gay and most people just don't like gay people. Sure...SOME people don't like gay people and maybe SOME people don't like him because he's gay. But he can't change being gay and you don't know if there are other parts of his personality that are turning people off. So you telling him that people don't like him because of this one unchangeable quality instead of getting to know him and actually finding out what it ACTUALLY is, is IRRESPONSIBLE. And it is DAMAGING---you don't know who is strong enough to handle hearing that and who isn't.
Look, I get it. The OP hasn't given us nearly enough information to figure out what is REALLY keeping him from scoring. But that doesn't mean we need to take the one thing that he did give us, probably based on his own insecurities bc again, society teaches us to hate ourselves if we're fat, and tell him for a fact that this is what his problem is. Because you just do not know. And based on my experiences (NOT narrow, I assure you) and the experiences of thousands of other bears, cubs and chubs across the country, what you are saying is FACTUALLY UNTRUE. There are guys out there who will be attracted to him BECAUSE he is bigger. And instead of giving the OP a complex, whether you all meant to or not, I think we should be trying to, I dunno, actually help him by digging deeper and giving him actual answers, if possible.
