Left swollen and sore after long (amazing) sessions.

Had an amazing session last Friday that I got to the 4 hour mark before it became too much and I had to stop.

I started with my mandatory 30-60min of just njoy seated light inward and upward strokes while squeezing base/center. I moved to the machine on the mustang for maybe an hour of self thrusting back rocking on my knees and the ottoman. After about an hour I tried moving up to the maverick.

As soon as the maverick was in, I can't help it but I'm immediately involuntarily pushing out with the reverse kegals. The pleasure starts to get extreme here and it's amazing, but I know it's not sustainable. It gets to be the point that it hurts too much and I know if I'm going to be pushing out anyways, the p-spot is way better than the maverick. My problem is as soon as I'm pushing out, all the lube evacuates and expelled out all over my towels/the machine.

I've had moments of where I can control the push and scale it back so that I'm pushing just enough to feel the pleasure, but allow the machine to continue to pump. But eventually something triggers and I involuntarily push with all my might and it stalls the machine entirely or I have to turn up the velocity. When it gets here it also basically starts a timer of how long I've got before I too fatigued to continue and I get too sore for foreseeable sessions.

This time around I quickly scaled back to the mustang and was able to find this sweet spot for almost the last hour. But that's still an hour of intentional pushing, paired with the sudden bursts of uncontrollable spasms pushing with all my might.  It was almost right at the 4 hour like 3hr 53min I feel like I hit a brick wall and I wake up from a dream and there's no sensations. I don't want to push, I can't squeeze base/center and feel pleasure. I don't even want to crank out a traditional orgasm.  Overall I'm really happy and I don't feel overly sore so everything is sweet.

No, now it's 5 days later and I'm too sore. I go to clean out with t the shower douche and just douching I'm hit with insane pleasureable involuntary expelling pushing sensations. It feels great but it's still sore, 5 days out. I decide to try the njoy and I can feel I'm swollen just inside the rectum. Normally I can get the ball of the njoy right on the prostate and just little strokes/pulses of pressure but it feels like 1.5-2inches of swollen walls from where it would normally make contact with the prostate. Meaning it's making me go in deeper, not the wall is thicker between the toy/prostate. But I have to physically go 1.5-2" deeper and then I'm only hitting a different part of the prostate. Not much pleasure if any so I opt to chill and let recover so I can hopes in having a good session this Friday.

I feel this isn't a problem aneros enjoyers get. I know I'm being too rough and I don't want to be. As I said, it's usually involuntary and when it is pushing intentionally I try my darn hardest to push the lightest I can't just to trigger pleasure.

I don't know what I'm asking but does anyone who have had similar experiences have any sort of insight they can provide? What worked for you so that you're not incredibly sore for several days after? I've had days where I'm sore after but I can still have multiple sessions and they build each session. Check my post history, I've had a few times where I go back to back while gaming so 3-4 days each time being 4-6 hours.

Right now I'm worried I won't be recovered for tomorrow.
