Fatpeter:
My wife now knows I like her fat. She has so now for a couple of years now. In which time she has put on 15-20 pounds. Not intentionally though I might add. The fatter she gets, the more I can’t keep my hands of her. I keep reassuring her she looks better with the extra weight, and that a lot of guys, though they won’t admit it love fatter girls. I feel like she is on the brink of intentionally gaining, and possibly wanting to really show off her fatness. I just don’t know how I can get her to that stage. Anyone have any advice on how I can get her there?
The previous comments are true in my experience, too. I would offer the following advice though: Share your attraction with her but don't make it focused on her weight.
You can't MAKE someone be comfortable with their body. You can only show them that you are comfortable with their body. If you objectify their weight, it will be the focus on their thinking. When they have moments of insecurity, it will become the focus then, too.
Just share your lust for her - her body, her whole self - not her weight.
