Sure, some men like their girlfriends to be hot and sexy, or cute but skinny, but they don't look on the other side, where overweight girls are beautiful too. They just might realize in the future that it's not just about the outside, but more importantly the inside where they can really be attracted to.
So I think that you shouldn't be worried about if you're not going to have a boyfriend anytime soon. Just wait till the right guy comes to you. =) (and btw, the people who tries to mock you are the brick walls that block you to your happiness, so forget about what they say or do.)
Try and enjoy everything around you and be cheerful and proud. That's what guys are mostly attracted to. =)
That said, as someone else on the post mentioned, there is a big difference between "overweight" and "obese". In fact, the people with the longest lifespans are in the "overweight" BMI category rather than the "normal" BMI category because the little bit of extra fat they have protects them from a number of diseases. That bit of extra fat on a girl is also what gives her curves!
Since most people don't really seem to have a clear perception of what "normal" vs "overweight" vs "obese" looks like, check out this gallery: http://www.flickr.com/photos/77367764@N00/sets/72157602199008819/
As too a few people who have commented on how they are overweight and cannot find a man, there are couple of things at play here:
Your attitude. Know you're beautiful.
What are the type of men you're after? Don't look at night clubs and bars. I met my girlfriend paint-balling.
Do exercise and attempt your best to be fit. I like looking good with tight arm muscles and a smoother flatter tummy, I also appreciate a women who does. This doesn't mean that you should look anorexic. That's gross. Seeing your skeleton can be a turn-off. Having a body that is not too hard and not too soft is what I think will help.
Use body liners and shapers to help when you're not quite there. If you're looking for a relationship, you'll have time. If you're looking to have intercourse, most guys don't care what you look like when they are turned on.
Overall, don't worry. Put yourself out there in all sorts of places. Its a numbers game. The more you put yourself in place where you can meet people the better your odds of meeting someone become.
Because it's unnatural and goes against nature. Nature says to pursue the healthy female and thats what makes us content. I have always been willing to date women who may have "thickened up" a little, but once she has rolls or flaps, no thank you, the desire is gone. In all fairness, the same is true for women judging men. Most women don't want a big fat man, most seem to be accepting of a guy who also "thickened up" a little as well, but I think when he has to lift his belly to wash the belly button, many women choose to pass.
My weight has gone up and down a bit over the years. I have varied by 40 lbs. I can say I have never had to lift my belly to wash though, it has never "drooped". I am told that means I have been thicker, not not disgusting.
Most men do wonder about other men who start out dating a large woman, this is just some inside guy info. We do ask ourselves and other buddies why is he with her, that's nasty. The truth is most men my friends and I know who date larger women, lack self confidence or ambition to care for a thin attractive woman. I have one friend who is big himself and he married a 250 lb 5-6 woman. he says he doesn't want to worry about the "BS" that those thinner women give him. Truth is, I have never seen him with a thin woman and I think many deny him so he is happy to have what he has. If it makes him happy, more power to him, but I would be lying if I were to say I find her attractive.
I think it's sad when I see men married to large women, sitting around watching porn of thin attractive women and then comment about how one or the other might have a slightly bigger behind than another. It's almost as if these men are in such denial they don't know they go home to a woman that is 2 or 3 times the weight of the heaviest actress in the porn. I had a friend in college that would pass judgement on every normal sized girl that he saw. He would comment on how her butt is too big or her breasts aren't in the right shape or whatever else you can think of, then later he would be having lunch with his girlfriend, and she couldn't fit in the regular sized chair and had to use a booth because she was too heavy for the chair. I truly think men like this get their physical satisfaction from women that are willing, yet have convinced themselves that they are with someone other than who they are. This is very sad in my opinion, if you love a large woman than love her and enjoy each other, but if you save your fantasies for the porn and judging the rest of the world, something is wrong if you think a 5-4, 130 lb woman is disgusting when your wife weighs in at 250 and you say you think the world of her. Just be honest, if you like them big, love them big. It's totally each mans choice.
That's why many men dont want to date fat women, our instinct tells us it is not good and for many of us the desire wont form. It's not personal, it's just if there is no desire, we can't force it. Would you prefer a man who says oh yes, you are beautiful but doesn't really mean it? Do you really think he is going to be faithful to you if your body doesn't strike his lobido? My g/f is very attractive to me and holding her intimately mades me very content. She is only 5-3 and weights 99lbs. Some men don't like that, but I do. I have no desire to cheat on her because I find she is the only one I want. If I had pretended to love a 200lb woman, as much as I don't want to be the cheating jack ass some men are, it would be difficult to stay faithful because I wouldn't really be crazy about her looks.
Good luck, there are men who prefer big women, but be careful because some men just settle for what they can get and will use you because they feel you are desperate. You want a guy that does worship your spirit and your body. Just make sure he is a man who finds large ladies attractive and you will be fine.
I am not attracted to overweight girls because it suggests any manner of things that I don't find attractive, mentally, in people. I also do not find it to be physically attractive in any way. I prefer an athletic build on anyone. Anorexia is also unattractive. I feel completely justified in only being attracted to fit people, and work hard to keep myself fit and healthy as well.
I do sympathize with you though, and hope that one day you find love. In the meantime, love yourself, no matter what, because that is infinitely more important than anything.
