In answer to the original question, yes I do get turned on looking at my own fat belly and huge ***. I don't know why, but I do. I'm straight and married to a BBW. We are old, so sex really doesn't happen anymore. I'm sure my gaining weight is taking the it's place. My wife must notice I have gained weight, but she hasn't said anything or made it an issue. But I have noticed she is more comfortable with her weight. Last year around this time she was actively trying to lose weight and eat better, not this year! Great post, thanks for asking the question.

Great job, I think your math is correct, though I didn't check it. I'm gaining for the fun of it. But speaking of bikinis, I was on a business trip earlier this week. The hotel I stayed in has a hot tub and pool indoors. I always bring my Speedo bikini cut brief swimsuit with me. I have to admit, I really enjoyed sitting in the hot tub and pool with my new pounds (5-10lbs.) since the last time I stayed there. Good luck, remember, "Stay hungry my friends!"

I felt that way around the holidays. I could easily gotten away with (no one commenting) eating a lot more than I did. I had set a goal of getting up to 220 lbs., I still haven't reached it, at least at my normal weighing times (first thing in the morning). I did hit when I was really full though. Nice thread!

I think that a mutual gaining relationship could actually occur quite accidentally or more likely unintentionally.
I have been gaining the last couple of years since getting out of the military reserves. I have put on fifteen pounds. I have "outgrown" many of my trousers and I'm getting thicker in the middle, not a hugely pronounced belly, unless I deliberately stick it out. My wife is a BBW and has been for many years. She has always been annoyed for lack of a better word with her weight and being out of shape. She recently seems to becoming my encourager. Always asking if I want seconds, last night she brought home a large pizza and a desert cake from a new bakery. She hasn't mentioned at all how much weight I have put on, but I know she has to notice. I deliberately stick out my belly while showering and dressing (45 inches!) so I know she can see how big I'm getting.
So I think a mutual gaining relationship can "evolve" over time, maybe accidental maybe to strong a word, but subtly watching each other gain a bit here a bit there maybe closer to a norm than society admits.

I still do sit-ups every weekday morning. I have gained ten or so pounds, now up to 218 lbs. I really can feel the extra pounds in the way! When I'm done I sit back and immediately inhale, I can really feel the shortness of breath doing the sit-ups.

In a similar vein. I have a story posted on my DA account, titled, "Feeder/Feedee Valentines" the story is about a day long food binge for a loving feeder, by her loving feeder. It might be in my stories here as well. DA account is fanedfox@deviantart.com.

I posted on this thread 10 months ago, stating I had a ratio of 1.02. I'm proud to say now that I'm at 218 lbs., 5'11" with a ratio of 1.04. My BMI has increased to 31. Big belly with a fat butt.

Your point on whether to drink a whole bunch at once or spread them out by having one a night over a longer period. I would go with one a night. Consistently adding extra calories is a sure way to gain, though slowly, but with consistent results.

Peanut butter, ice cream, frozen pizza, to name but a few.

Fatcutie; Thank you!
