I have entered subspace a fair few times, i have to say it is a wondrous feeling, its when my mind stops resisting, and accepts everything my master submits me too, i feel a relaxing of mind and body, and my mind drifts away, lost in the experience, pleasure and pain truly intermingled inside my brain, and a real calm overtakes me, while at same time i can reach a level of pleasure unobtainable any other way, i find it hard to orgasm normally, but once i reach this place i can have strong orgasms.
