Nair works well. And HRT will help in that aspect.  I have a lot of body hair, but most has faded and thinned. So much so that my GF has not said anything.  I also can shave those areas because with HRT I can reach them.
I have a small patch in the small of my back that gets long, but I have not checked it as to color or type.  I just shave it once in a while.  Get an SO to help with the body shave, but you might need to ... ahem ...
