I’ve read the above algolagnia link.

Although I do derive sexual stimulation from physical pain in my erogenous zones, I don’t interpret the pain as pure pleasure.

For me, the pain hurts, but is also arousing and exciting.

In extreme cases, the pain is a challenge, a battle between prolonged over-sensitive sexual excitement and physical torment; a fight only resolved by ejaculation, or by my submission to the state where the pain is everything and my mind floats above it in a state of serene calmness.
