I agree with others above, but I'll add that for me ice cream was a major contributor to my gain. High in calories, easy to eat and delicious.

Yup, such an exhilarating experience to go out showing off all the new fat. Last year when I was at my max (~250 lbs) after having gained 40 lbs in a few months, I would go to the grocery store, restaurants, and even the beach wearing outgrown clothes (which was everything I owned), buy lots of food, and just eat and eat. There was no hiding my belly, even in sweatshirts haha. I got lots of stares and I enjoyed the combination of shame and liberation

Both! I used to mostly like the idea of it for my partner, but more and more I like the idea of it for me... sometimes I even think about what it would be like to have a fit partner that encouraged and teased me about my gain.

I echo what others are saying about major health problems though. Such a tricky "fetish"!

I don't want myself or anyone else to be truly unhealthy or have major problem, but I do enjoy minor forms of being unhealthy like getting out of breath and slowing down, being lazier and out of shape, general obesity, belly getting in the way of some activities, etc.

Its totally worth it though! Another PRO: two dinners, two desserts

I like your list! Here are mine:

PRO:
Getting turned on
Eating anything and everything
More stares/comments for being fat and gluttonous
Outgrowing clothes
No more working out
Forgetting about what society says

CON:
Tire more easily
Less looks/interest from women
Possible health issues
Having to go shopping for new clothes
Spending more money (food, clothes)

I would say just enjoy yourself and see what happens. I gained 30 lbs in 3 months and I don't think my girlfriend even noticed haha. On the other hand an ex started complaining after i gained 5 lbs (clearly that wasn't gonna work out for me).

I have eaten a dozen Boston Creme donuts in less than an hour. Probably could have eaten more

Its always great to see others with their bellies out in public. I really enjoy letting mine be on display too, but not if close friends or family are around (too judgmental). I've gone to the store in out grown clothes or to the beach with no shirt and enjoy all the stares

I have always liked watching other gain, and in the past year I was an active gainer too. Mutual gaining would be great.
