>You have a lot of crosstalk in the parts of the brain
Genuinely don't think this is a thing (in general, at all, ever, under any circumstance besides grossly invasive surgery)
>You have a lot of crosstalk in the parts of the brain involved in those 2 sensations
unless by "in the parts of the brain" you mean the nerve in my abdomen that are virtually on the other end of my body to my brain.
It's definitely a local reaction that doesn't take the time of something going up to the brain and back down anyhow. It's a sudden muscular contraction like touching a hot kettle unexpectedly.
>if it's painful I would take care in not touching this area while cooming, or learn to stretch and relax this muscle group when you fap, not all muscle groups feel good when tensed up for too long like when in the middle of an orgasm.
It's the good type of pain. Again, and quite surprisingly, it isn't very sexual in nature (it isn't really pain either, just a surprising reaction).
Conventionally, I like put off anal till after exercise cos it's my experience that you feel the tired muscles more and it's better, especially when you're actually cumming, but if anything I'd have said that that usually reduces the intensity of the external-stimulus reaction in the OP. At the time of making the OP and having the experience described, I had been slacking though. It's possible that the maintenance (exercise) work I'd been doing did actually contribute and that it's a consequence of doing this work and not unwinding the fascia with warmup/cooldown stretches from a more structured routine. Alternatively, may have been contributed to by having been awake for a long time.
Either way, all my questions still stand.
