I don't know in what context you are using "cumming" and "orgasm." If by cumming, you mean ejaculation, then they are not the same thing for a guy. Ejaculation is the physical act of releasing sperm, while orgasm is a whole nother ball game. It just so happens that the two normally coincide, so most people assume they are the same thing.

For women, obviously the same dichotomy exists between ejaculation and orgasm.

You see these shackles
Baby I’m your slave
I’ll let you whip me if I misbehave

Tie me to the bedpost

I like it rough
cause I'd rather feel pain than nothing at all
