I have been trying a missionary style position with a girl that I’ve been seeing. I don’t have enough mobility to move my hips so typically I will line up with the edge of my bed and use it for leverage, but the problem is. Because I’m disabled. I leaned my left a little bit and that usually ends up with most of my weight on one of her legs. I’m not strong enough to push myself up. Is there something I could be doing or a device I could get to not crush her leg in this position?
