I just remembered that I have been trying a new strategy to have more sex in the relationship with my spouse. When we do the sex routine, I bring my laptop into the bedroom and set it up next to my bed where only I can see it. I setup a slide show with porn and let it run. Then I get my wife and do the sex thing. It is great being inside her with her legs way up - usually somewhere in front of my face - and I am riding her watching my specially selected porn pics. It gets me off a lot more. We - in situations like this - need to keep being creative to keep it up!
