In my experience, bigger girls are better in bed though that might be because the larger women i've known have also been taller and stronger. My slimmer exes were maybe a little better when they were on top and could sit on my face with less risk of suffocation. But in every other way, give me curves and a woman powerful enough to enjoy long sessions of passionate missionary on a daily basis. Also, the only women i've know who seemed to really enjoy giving (and gave the best) hand and blowjobs were fat. Also, the slimmer girls were the least confident naked. A tall, curvaceous girl with a big smile, her shoulders back, tits thrust out ever a flabby belly and huge thighs is way sexier than a hunched skinny girl with a toned figure looking sort of awkward and self conscious.
