Why are big girls expected to be okay and HAPPY to use their weight during sex, such as facesitting and squashing? Speaking for myself, I'd prefer the kind of sex that would be asked of me if I were skinny.
Then you should lose the weight, Lyric, because you're in for a bummer of a life. Fat sex is had with fat bodies. Those qualities that make you fundamentally different from thinnies are what attract chubby chasers to you in the first place. If thinsex is what you seek...the extra flexibility or a partner who can lift you up and fuck you against a wall, you want to slim down. Big girls are expected to be happy at anything, not just sex, because only perverts want to fuck someone who isn't confident. Your weight is what you have so, at least for the time being, you should use it. Thin people do facesitting too, you know. If you don't want to squash, you should find a more dominant partner, as squashees are usually submissive and want that ultra-confident goddess type to pummel them with her weight and physical power. If you don't decide to lose the weight, you're stuck with what you got, and since any fat admirers you'll be fucking will love it, you might as well learn to as well. Find creative ways to use those crevices and wobbly bits, enjoy the uniqueness of it. Guys with small dicks wish they could have sex like guys with big dicks, you know? At least you're afforded the gym option.
