People feel an important need to be visually aroused to really enjoy sex. I can see clearly why someone would not want to look at love handles, cellulite etc while having sex. A friend once said that he didn't like having sex with heavy women because it was a lot of work trying to work around their extra weight and he hurt his back and it was way too much of a workout.
I disagree about heavy men being with beautiful women. This is rare. The only time this happens is if the man got heavy sometime in the marriage or he is wealthy or was a childhood sweetheart. These things make a big difference. But no, a heavy man will have just as hard a time as yourself.
