It is alright for them to be fat and chubby, they are considered cute and fluffy if they have some curves. Men, on the other hand, either be it gay or straight do not have to keep up with the same standards.
Why you ask? Well first, the standard for men is not the same as women, it is quite alright for men to have some ounces of weight as compared to women are pressured by the society to maintain skinny legs and big boobs and flat stomach. Thin and slim are out of date and it is now fat or chubby men who are mostly desired especially by gay men.
