Oh.. I totally do all of that. I let myself go rather than being self-conscious so even though I generally lose the ability to talk when I go into subspace... However, groans, moans, lots of shaking and the occasional "fuck" are things I definitely don't hold back on and are not consciously done.

I do admit that I will even beg or reach rather than staying disciplined when I get totally crazed for something (and this does not make me feel guilty), so it is in the form you are talking about.
