We don't do either of those. My theory is that the brain is your biggest sex organ - so you do what it takes to keep it 'engaged'. Sure porn will work for that, but my partner is turned off by it.

For us it's the desire to please each other. Adding new toys and techniques is a nice way to keep it from getting too repetitious. So every month or so, we add a few new toys - or try to use old toys in a new way.
