You know, I think in my case that ed was a contributing factor. I think he blames me for it. I actually think that's what he means by there is no spark. He seemed to feel the spark a couple of weeks ago when he actually carried me to the bedroom for a romp and had no problems.
Last weekend we went down that road again. He had no problems. So being a smart ass, after I let him rest a bit and have a cold one I asked him if he was ready for round 2. He said no he was tired and I told him I was sorry he couldn't keep up with me. I know, that's mean, but hey, it's true. And I needed to get in as much as possible in the limited time I had available.
He said to me once, I hope you don't think I'm using you. No buddy, but I hope you know I'm using you.
