This is one subject i love to talk about because i love sub-space. For me many things will send me there, If my Master kisses me hard and will tug my hair to pull my head back and gives me that look i can feel the start of my decent into sup-space, everything around us starts fading and i start getting that numb feeling. I go very deep when i am being whipped or spanked hard. It feels wonderful, i can feel myself starting to leave my head and i can hear everything going on but i can't talk, i can hardly move on my own other than squeezing my hands in a fist or rolling my head, and all i can do is moan and grunt. It can be dangerous to go as deep as i do as easy as i do, it took alot of time and trust for my body to be able to totally let go, if you are doing pain play and you space out you can't tell you Dom when to stop, me myself i don't want it to stop, nothing on earth can make me say to stop when i start going to sub-space. When i'm in sub-space i don't feel the pain anymore, all i can feel is my body as a whole and its numb and tingly and when i feel something like the belt or His hand it sends something through me, i cant explain what it feels like, like a beautiful numbing tingling lightening bolt. I get to a point and i don't feel anything except a feeling of being so calm and warm. It can take me 15 minutes for my Dom to be able to bring me down or it can take hours for Him to be able to bring me down, all depending on how deep i go at the time. This is where aftercare comes into play and in my opinion is something that should always be done, even if its just cuddling and talking. My aftercare consists of anything from cuddling and talking to being given a bath and being washed and then given a whole body massage, no matter what the aftercare is He is always telling me how good i am, how beautiful i am, how he loves me and the way i respond. Its wonderful to be brought down from space by someone who will take care of you because sub-space is very emotional. I have cried and laughed when i am being brought back down and all my emotions hit me again. Sub-space is wonderful, make sure your Dom knows how to keep you safe. And remember sub-space is different for everyone. Everyone experiences different things while in space, the most common thing is the wonderful feelings and the disconnect from yourself.
