I'm already having this problem. I can still do it but have to bring my knees really far up and bend far to the side, making it hard to breath. The amount of effort and discomfort it causes is also making it hard to get off. I have a feeder friend who visits and having them pleasure me was such a relief and felt amazing. Can't wait til i have a feeder and am at the mercy of their need for me to eat until they are satisficed enough to allow me to come.
