I know for me and my husband, we're overweight and older and I personally don't enjoy getting into "position" :-) and assume it's probably even a bit harder for an older guy. I think I'm much pickier about cleanliness issues than he is though, we have so many cracks and crevices that I could see that "spontaneous" acts could get a bit less enjoyable/appetizing over the years as libido changes. You all have a shower big enough to take showers in together; that might help? That and then some room temp drizzled chocolate in strategic places afterward? ;-)
