When I was doing the May masturbation challenge (must come at least once a day, must be creative) my orgasms were crazy powerful. Now I don't wank even half as much and they are meh. There is something to that.
for me, I found that my biggest, best orgasm happens when it's been a few days since i last had one AND if I masterbate till i almost blow but stop. A day or two of that and when i do release, you better have safety goggles on.
Before we started prostate play, I'd have more intense orgasms if there was a day or two between goes. Now it pretty much doesn't matter...the p-spot orgasms she gives me are total body, mind blowing every time. Ones I give myself are a bit less intense, but still great, even hours apart.
