I just like a nice firm bubbly-butt. It is what gets things churning in my plumbing. That being said, when it comes to marathon fucking or power fucking, the hole and its' immediate vicinity should really be shaved smooth. Hair will have a tendency to become abbrasive during hours of fucking, even with a condom on. So I guess my answer is that as long as the hole is ready for root, the rest of it can be smooth or furry. I really do not have a preference.
