My guy was hesitant about it at first, but lots and lots of compliments and physical attention, especially toward the belly, helped lots. What really seemed to do the trick was letting him find my bookmarked.. ahem.. material - videos, mostly, and some stories, all involving fat men, stuffing, gaining, 100% weight gain centered. He was really surprised that there was no element of normal sexual stuff; I guess he assumed it wasn't exclusively about the weight. But he's really gotten into gaining since then.
