I think someone would need a crystal ball to tell you about immobility. I've seen some younger people well over 600 at average height who could get along quite well. I've seen some people struggle at 300 pounds. Remember, that as you get older, the less likely you will be mobile. If you are injured, you may lose your mobility. So, it is not only weight, but age, lack of injuries and just plain old luck to stay mobile. At your height, you should be OK at 500 pounds. Slow, but mobile.

I really don't understand that part about whose are bigger. What difference does it make? Some women have big boobs, some have little. But it has nothing to do with the size of their man's boobs. Are people saying that a man with B cup boobs can date only a woman with C cups or larger?

According to the fashion industry, it is anyone size 28W or larger.

I guess it depends what you expect. lol

I'm not into guys, but looking at the pictures here, you can be on this site and be into men, and still get some big old titties. lol

Someone can probably be more technical than me, but some people have fat inside of their muscles and are tight, others have the fat outside of their muscles and are flabby. It is genetic. You can't control it.

I am an FA, but some of the thin women here are really cute. Obviously no match since I am not very large (I am older and married anyway), but I hope the thin women keep posting pictures, and stay with FF.

Female hormones have a lot of side effects. Besides blood clots and other nasty things, it will probably make you impotent, shrink your manhood, etc. It won't just give you fat breasts, it will give you female breasts, with milk ducts and nipples. You'll look like a braless woman. It will change your body smell, and will change your personality. People will probably mistake you for a woman, even dressed as a man. That seems like a lot to go through for a bigger butt.

As has been discussed a million times here, you can't control where the weight goes when you gain. If you are prone to gain weight in your face, you're going to have a fat face.

Anyone who gains weight on purpose is going to have to deal with friends and family and society. That is pretty much a given. If you have a thin skin, then gaining is not for you. Some people get turned on when people hassle them about their weight. For people who are not like that, then you need to set boundaries as to what is acceptable to talk about, and what isn't. Whether you are fat on purpose or not, you need to let people what discussing your weight is not acceptable. Unless you live with the person, you may need to leave if they do not respect your wishes.

I consider myself a gaining admirer. If someone wanted to be fed, I would do it. But the enjoyment for me is the gain, not the actual feeding.
