Yes, it happened to me as well. I guess not full blown all the time but several times gained a good 40 lbs. and got a huge gut.
In my case it happened accidentally and then when I noticed... “I know kind of crazy not noticing 18 lbs. for a good two+ months that I gained”.... but after I noticed I had the arousing desire to continue to get as big of a gut I could. I became my own feeder. The reason was I believe for the lack of weight gain on my wife and so the most arousing thing was for me to get my gut so big she would comment, tease or even scold me for getting so big. 18 lbs., 25 lbs., 35 lbs. she still said nothing so I kept going. She began making me bigger portions with her cooking and always loading seconds on my plate. I began to think she either liked my new big gut or she wanted me even fatter. Then I thought as she was gaining at the same time maybe she wanted to fatten me so I stayed fatter than her and she felt comfortable becoming g fatter together. That was what enticed me the most at this point “Mutual Gaining” even if we were not discussing it directly we were both getting big and eating more and more and getting bigger.
So you probably won’t be as shy if it happens with someone you are with.
