I see it as a sign of how fat I am. In an ideal world my cock would be totally out of sight and not able to achieve penitration. Sex is a calorie burner anyway eating and oral sex is much more fat friendly.
Don't forget fingering and having your partner rub themselves over your fat.
And of course, for anyone with a penis, they can get off with your fat folds or navel.
And pegging. Some strap-ons are also able to stimulate the wearer.
Good times all around, really.
