Sure, they're very comfortable to feel and I like how they look. I've dated one before if you count overweight as fat. The experience was nice and I would definitely do it again.
However, I do have a limit if they're very obese or morbidly obese especially at my age, since people tend to gain weight as they get older. Being that heavy can very unhealthy, so it would heavily concern me.
Fat is kinda an umbrella term. Would I date a chubby girl with a bit of belly and thicker thighs? Hell yeah, more of her to love. Would I date a morbidly obese woman who has a hard time standing for long periods of time, needs me to wash her folds and hasn't seen a green food since 2008? Nope.
No. Call it shallow but i've been known to walk "too fast" for many. I'm walking my normal pace, even in school, i'm passing up my friends that were taller than me. Not gonna be wanting to wait for a mofo to catch up with me when I am walking normal.
