I've had this before. To be honest I've never really kept track of it, because for me it wasn't solid years or whatnot, rather just I'd notice the last several times/weeks were rather humdrum, with solo or with my wife. Without sounding gross, the sensation was like going to the bathroom in the morning. Just a sense of relief. Not the twitchy goodness it "used to be". I did notice this was much more prevalent when I was on a mild antidepressant, but you stated you're not on anything.
And while yes I did read your request of not giving the "all in your head", but at least for me I noticed the more I remembered it happening, the more it would happen. I'd almost trained myself to have mediocre orgasms.
What works for me is I basically saved a "special trick" to jumpstart myself. It wasn't until finding this site that I read about prostate massage, so one day in the shower I swallowed my macho ego BS pride and tried it out. Just for the sake of it being such a new bizarre thing to me instantly turned everything around. First of all it was like an orgasm button, and made it instantly happen. Second, just that "new and exciting thing" thought was enough to make regular sex/solo play fun again.
I hardly ever do that massage. I don't want it to become commonplace or worse a requirement. I basically use it as a pick-me-up when things seem drab. It's almost like flipping a mental reset switch for me now.
