I think chubby girls have it easier getting laid than chubby guys though. Quite a few men have a fetish for bigger girls, but I've never heard of a fetish for bigger guys.
At any rate though... and this may sound cold, but it's the truth: You gotta be in the same shape as the league you want to play in. You wouldn't expect a pro football team to give you a try out if your football experience is playing Madden... and if you don't take care of your health and your body, you can't expect those who DO take care of theirs to want to have sex with you.
I know it's not easy - I was overweight for quite a few years, so don't think I don't understand where you're at. Then one day I was like you know what, I'm not happy like this. It's keeping from being able to do the things I want, and being able to do the people I want

So I started eating better and started exercising. It was hard at first, but the human body is adaptable. You'll get used to not eating all the time, using it as an antidote for loneliness and boredom. Keep eating normal size meals, and you will eventually get full from them like a normal person and not need like six slices of pizza (like I used to) to feel satisfied.
Its your life, it's in your hands. You have the power to change things and make the life you want, a life where you're in shape and have lots of great sex. It's up to you
