For the subs - Have you experienced tears like I have when playing hard? Have you pushed past the tears, and if so, do you go to a more calm and peaceful zone?
I have cried rather often, but I very rarely have experienced that as emotional. It mostly felt like the way one might cry if you kick against something sturdy and brake your foot. I quess many times I would have been able to hold back the tears, but it felt so very right to do. And for me it was also exposing myself, which was hot.
Just sort of a catalyst reaction to pain. That "feeling blank" I rarely experience after physical torture, much more after psychological torture. After heavy physical torture I feel really good. Mixture of being horny, proud of myself, loving my master and feeling nearly 100% mentally exposed.

Hope that makes sense in english
