After 1st climax the 2nd go-around and climax are significantly better

I am a mid-20's male.

is it normal that after achieving ejaculation (through any means, solo or with someone), if I decide to keep going or do it again within a certain time period, everything the second time is significantly better?

For instance, when I masturbate, if I continue after ejaculation, my penis becomes ultra sensitive to touch and sensations. Oh MAN it feels MUCH better. My erection is also always stronger, harder and fuller than what it was at even the climax of the first time. It even reaches a higher angle the second time. And while the second climax doesn't have the 'shot strength' of the first one, the amount is roughly the same, but the 2nd climax FEELS 100 times better... "the house is on fire right now but this feels so good I can't even stop" better.

The time frame for me to get the second one in I've noticed is about 3 hours? Like, if I wait 5 or 6 hours later then the 2nd time doesn't feel anything special. But any time within about the first 3 hours is great, with it being the best if I only take a couple of minutes before going into the next one.

I ask this because I hear that guys lose performance strength after ejaculating? And they don't get it back up as easily and it's just not as good? But with me, the second one stays up better than the first and it's just way better than the first time anyway. I almost rush to get the first one out of the way just so I can get to the amazing second go-around.
