I was with my partner in the bathtub, we were trying a few different positions and she ended up underneath me, under my balls looking up at me as I was sitting over the edge of it. She now wants to get that view more often, and in a more comfortable position. Has anyone got any ideas for how we can achieve this? Should I just get a sex stool? The only reason I'm apprehensive is that they seem to be quite pricey!
