Most Helpful Girl
Everyone has their own preferences so it's not possible to generalize and say all or even most girls like any certain type of guy. I like chubby guys but my best friend likes lanky guys.
Most Helpful Guy
believe it or not, women are generally not as concerned about physical looks in comparison to how guy are. If she likes you she obviously sees something special in you and I wouldn't worry about your physical appearance so much so long as you have good hygiene. You're probably what most girls refer to as a chubby hubby, they look at your weight as just more of you to snuggle up with and keep them warm.
