While a cool down does sound theoretically correct, and correct me if I’m wrong on this, the penis is a soft muscle and doesn’t react the same as a typical muscle; not to mention that your shoulder and knees are joints which consist of cartilidge too i believe, and if you got joints in your penis, bud you got bigger problems. I’m pretty sure after PE your penis doesn’t swell up as much, or at all, as a damaged shoulder from a pitcher. (I know those are just examples, but I’m gonna pick on them ne ways). Your shoulder isn’t meant to swell up with extra blood, but your penis is, in fact that’s how an erection works. Not to mention that if you’re getting bigger down there you’re gonna need more blood to flow there in order to fill up a bigger erection anyways. While cooling it down may feel like it’s better, it does draw blood away, maybe in a stretched state it would work, but if not then I can’t see it being any different, or better, than a warm down. Heat tends to loosen up bodily tissues, where as cold tightens it. Mind you though, on that note it may be good for counter acting base skin stretching and turtle-necking, but that’s just speculation like the rest of this lol. Also, you say people talk about the blood flow thing too much, and yes blood will flow there regardless, but the lower it hangs (ie the bigger it is) the more blood will be circulating, and the more nutrients, blood cells, etc, will be carried there. Since it’s the only thing relaly circulating all over your body, there’s no other way, and it only makes sense that more blood flow would help.
I have no proof of any of this, it just makes sense to me.
