Better have a lot of food or money to buy food.LOLOL.

Dip your toes then its the only way to find out.
How to approach someone about this is to ask.
If this person is your wife or GF then just be honest with them.
Communicate your desires.

When I was an active gainer my belly was pretty much round and sat up high.
I lost 120 lbs to have ankle surgery.
I gained all the weight back over a few years and my belly was jiggly and soft and I developed a double belly that hung down.
Maybe it was because I lost weight and gained it back.
I do love a hanging belly on a guy.

OK

If she is doing other guys how is she your girlfriend?

I suffer from compulsive overeating disorder so yes I can relate.
The excitement and fear are part of it.
Binge eating I have done as well so but both are not a regular thing, the urges come and go.
There are times when I don't want to gain and there are times I do.
There are times when I have trouble and get a bit out of control.
I know its just a phase or urge so it will usually wane.

My BF has some pants that have an elastic waist band and he says they are comfy.
They are not dress pants or jeans kind of in between.
His dress pants he buys at a big and tall shop and they fit him fabulously.
He only lets his belly hang down when I ask him to.
I love it when his belly sticks out under his T shirts. So so hott.

Perks for me are:
I can eat a lot in public and nobody says anything.
I love being soft and squishy.
Keeps me warmer in the winter somewhat.
I love the feeling of squeezing into a tight pair of jeans so much it gets me off sometimes.

maybe I shared too much LOLOLOL.

I'm a fan of a man with a fat ass.
Thats what first attracted me to by BF.
He has thick thighs that rub when he walks too.
To me he is the hottest guy I know.
Thick around the middle and has the cutest back fat roll just above his belt.

No need to get so defensive OK?
I am not here to argue with anyone.
