A vist to a swingers club will take care of her weight fears. It's not just the 'beautiful people' who are there...it looks pretty much just like the people you would see at the market. All shapes, sizes and colors and they all can find people interested in them. However, this has also motivated others to improve themselves as well (worked for both of us). Also, now that you have taken the first step, the next step is to set your limits and boundaries, whatever they may be. Keep in mind that these will be a fluid, ever changing thing, however, never exceed them once set and the only time they can be modified is outside of a sexual situation and only if both of you agrees on the new settings.
