what words do you guys like to say when you cum? I normally like to say "im going to bust a nut" or just simply say "jizz".

often use the expression 'going to cream'

I usually say "I'm gonna cum." Then "oh fuck. Oh fuck."

Yep, me too. If I'm at home then I am very loud when I orgasm; I have no inhibitions whatsoever about being heard by my neighbours or if I have friends staying over

I should try to use the expression "im going to empty my balls!" lol

You took the words right out of my mouth!

"Ahhhh" and "Fuck" or "Fuck yeah"

I have to be quiet when I cum most times, but if I'm alone I've very vocal.

I'm goi to cum. Then Blasting my fuckin nut

Usually "I'm gonna/going to cum" followed by the name of the woman I'm wanking to at the time. The words "fuck/fucking", and "Oh shit" are usually somewhere in there as well!

I mostly moan. Loud and deeply.
I dont know how to explaing the kind of moanings I do, but as I wank, the faster I go I pass from closed mouth soft "mmmh" to loud and open mouth "ahhh".
Usually, when I cum, then the open mouth "aaah" turns into a closed teeth "nnngh". The harder I cum, the louder it is.

if im just stroking, usually just grunt out 'fuck' or 'shit.'

with a partner I breathe out 'I'm going to cum', thrust a few more times and grunt through the first few shots inside.

Usually: "Oh yes, Kim" (Wilde)

Fuck, damn, hell, shit, mother fuck, etc.

usually "mmmmmmmm............ open your mouth! put that tongue out for me..." then groaning as I shoot my load!

Mostly, "Fuck Yeah!
