I remember reading somewhere about 10 years ago that "fat porn" was one of the fastest growing segments of the porn industry. And it didn't surprise me given the fact that so many guys were interested in dating me during HS and college.
Also, during college I worked part-time in an adult novelty and video store and what we referred to as the "fatty fucker" videos were always among the popular rentals. This was the early 90s and we only had 1 or 2 fat porn VHS videos in the store at any given time but I remember them always being out for rent and it was kind of a joke around the store. See it's okay to fantasize about or get drunk and fuck a fat girl but taking her home to meet mom and dad or worse yet,...your buddies,.. THAT is something different altogether...Not cool
