Here's a question: Why is it that once I cum, my mind completely shifts out of the horny state I was just in - suddenly the pictures I was looking at and sexually drooling over are not of interest.. It's a change of personality that takes place in an instant!
Sounds like exactly what I feel like at that point, and a pretty standard male occurrence. It's happened to me ever since my first orgasm at age 15. I've read about it occurring to many men, but still not clear on the reason or mechanism, though it may have to do with male refractory period, sort of turning off your libido for you until you're able to go at it again and orgasm. For me, it has essentially the same effect on my kinkiness. As soon as I orgasm, my interest in whatever kinks I was using to stimulate the orgasm disappears and doesn't come back until my libido starts up again. I'm 68 so it may take many hours or a day or two to re-ignite my interest in orgasms, my partner, and kinks. When I was much younger, my refractory period as well as libido and interest in kink took much less time, sometimes almost immediately.
Back when I had a real person, my ex-wife, as a switch Domme who loved giving me erotic enemas mixed with our other kinks, this lead to an interesting practical application. She'd typically dress me in complete enclosure rubber and sneakers (2 major kinks), fill me with an enema or two, and make me hold it for a couple of hours while we did sexual things, climaxing with me giving her orgasms. Then I'd usually have an orgasm with her help (PIV, manual or oral) and go empty and change clothes out of my sweaty rubber.
Now if she occasionally wanted to really push me in my submission and make me stay in rubber holding the enema overnight, she'd usually make up a reason to deny me an orgasm till much later, usually morning after waking up (even though she had her orgasms already). As a result, I'd still remain extremely horny, spurred on by my kinks, the rubber and sneakers and enema, and maintain my arousal and desire to orgasm. It would also keep me being enthusiastic if/when she woke up in the middle of the night and insisted I give her another orgasm. In the morning when she decided we were near the end of her dominant role, I'd orgasm and then soon after go empty myself and get out of my kinky rubber clothes.
