A fairly thoughtful man just asked a fairly thoughtful question. He asked, "Do most men just want to poke women, or have some of them grown up along with you?"
This brings us to the subject of how we portray fat people as they have sex or make love.
I myself tend to describe curves and hills and valleys and softnesses. This does not mean that fat women cannot get fiery and determined and angrily passionate. It means that many of us are just learning how to talk about fat women as they make love. We are also learning, at the same time, to describe beautiful fat women, and the beauties of fat women. This goes for fat hot men, too.
There are other people who write about this. Hanne Blank is certainly one. Rebecca Weinstein and Virgie Tovar are others. Elle Hill/Lesleigh Owen certain does so, as well.
We have so much to learn about writing about sex fatly, about writing about fat people in sex and love.
