Obese women are fantastic for short-term, no strings attached sex. They often do things sexually that regular (normal weight) women won't because they know they have to do that something extra to get men. And I've choiced on that in the past, but for long-term, you need to know that the increasing weight gain and health issues will cancel out any advantage to staying with them. And from two guys I know who went that direction with a long-term relationship with obese women, the sex dries up the heavier they get because of lack of energy. Think it through.
