My premature ejaculation gets better with exercise where if I'm like A) not suffering from symptoms of depression + clinical anxiety issues, B) healthy diet, C) exercise, this means often times I can do multiple rounds. I've had this when I didn't have any of the A, B, C criteria I just listed too, it's just a bit more rare. There's also drugs that have been said to "eliminate" or reduce what's called the refractory period, which is a phase of disinterest in sexually stimulating objects so to speak, and a physical sense of tiredness accompanying it.

There are drugs which in certain people can effectively eliminate this sort of response most men or many of us get upon reaching ejaculation and oftentimes orgasm. There's also the matter of ejaculating without orgasming. So, for me I don't ever pre-cum and I tend not to cum a lot. I'm going to go out on a limb and claim I'd be at the lower end of the threshold of production for semen, where there are men who have a condition I think hyperspermia where they produce shit tons of it.

There's a channel called yummycouple I think on a tube porn site where it's relatively clear that's what's going on. There are different factors that can play into this ordeal, and these I've listed are some. So, let's say someone has a high libido, high-very high semen production, and low refractory period--just by nature--you might have someone who could have sort of hentai tier experiences in sex in regard to considerations people have around virility.
