Well, I can't say that I agree. Orgasmic space, for me, while it can certainly be coupled with sub space, can be separate entirely from sub space as well.
Again for me, orgasmic space is an intense frenzied awareness of myself while orgasming. All else is blocked out except for the want of the next cum. I can get to O'space on my own, without any Domly triggers whatsoever. Can't do that with subspace.
Yeah, two totally separate things for me.
