I'm a fattie and I look at sex as nothing but a big all you can eat buffet. Big girls have big appetites.
And where as some of you were mentioning maybe us fat girls were better in bed because we felt we had to push things to the limit to make sex memorable and strive to please our partner because we don't have as many opportunities as our thinner counterparts, maybe be true for some it's not true for all. I think confidence and comfort plays a big role in enjoying sex regardless of size.
I know I'm fat and it's not goin anywhere anytime soon. And I reached a point to where I accept what I have and what I don't. I'm content with myself. So with finding comfort in my body came more comfort in the bedroom.
As for having sex with a fat girl, I can't vouch for that, never tried it. I have fucked only one fat guy, he was probably 25-30lbs overweight and the sex was fantastic. I think it was mainly due to the fact he loved X and after taking it, we'd have sex for hours.
So there's my two cents
