Yes. Yes. Yes. I’m an athletic person who madly loved a person that felt like a “fat person” as you describe. He was and is (wherever he is) amazing. In all of these ways. Impossibly amazing sex no matter what body he had been in fat/thin/tall/short. Body size doesn’t change a devoted lover. Didn’t change the breadth of his love. Didn’t make him less marriageable. I didn’t land him, but I hope some lucky woman has. I also hope that she has better luck at convincing him of these things that you are saying than I did. Because for “fat” people, I think these less than feelings are too far ingrained.
