Do you have explosive orgasms?

I've found that the amount of my orgasm roughly corresponds to the level and length of arousal I've experienced. Work a quick one off while taking a morning shit? Satisfying not a gallon of cum. Watching porn for a few hours and then working a quick one off, more intense, more volume.

I've several times where I've either had sex or masturbated for a prolonged amount of time and had considerable more cum and a significantly more intense orgasm. It's almost like I've had multiple mini near orgasms and then one final massive orgasm. One time this ended in what I would call male squirting, I had to look it up after it happened, but I literally hit the headboard with a mixture of piss and ejaculate.

Anyone else have a similar experience?

Yes. This happens to me as well.

My wife and I have both found that if we wait a little longer between orgasms, the next one is more "explosive" or at least it is much stronger.

Additionally, if you wait a little in between, it's much easier to reach the orgasm. That might be a trade off between quality and quantity.
