Things work well for me on Sundays. Other days, not so much.
During sessions on post-work weekday evenings, after an initial jolt and a fast spazzy run-up to a pale, weak, anemic orgasm, I didn't get much going. Any waves that came around felt like two or three dissonant notes that warbled around but never quite synced into one pure tone. When I got that far, I either couldn't relax well, or I relaxed too well and fell asleep.
That's not entirely bad. A quick early evening nap is pretty satisfying in its own way.
I don't completely understand what my problem was on this Saturday, or previous Saturdays. Figure it should have been a good time for recreational activity, especially one like this that is, so to speak, open-ended. Perhaps because I see Saturday as my day to finish the previous five days of neglected tasks, that's carrying over into areas where it's not useful.
But Sunday was delightful. I get three sessions in, starting almost as soon as I awoke, and none of them was a real dud. Each session on its own feels good enough to make me come back for more. I can't yet achieve waves consistently, but even my inconsistently occurring and short-lived ones are astounding.
