Certainly, I thought this was a given.
when I was at my fattest I would stuff myself with insane amounts of food all day and by the evening when I would shower before bed I would masturbate with my huge gut all soaped up cupping & shaking as well as resting my hand on top and caressing my huge massive gut.
When I was this big during this phase it always always seemed like I was always at least half way erect if not all the time.
