Just how sensitive is it?

A few weeks back, I tweaked my neck and back and have been unable to use my go to position - on my side.  An inclined position when lying down helps so I came up with this. Imagine a normal, 3 cushion couch. I prop the first cushion up and also at an angle. The next cushion i prop up at an angle over the third cushion for my feet/legs to be elevated a little. This leaves an open area between the cushions of 6 or so inches where the toy and my backside are elevated enough to be free to move. I always lay a towel over the cushions to protect them. 

Here's the sensitivity part. When I start out, I am raised up at the edge of the first cushion with pillows under my neck and back. Naturally, as things progress, your body is moving, thrusting, gyrating, as it normally does in a session, and it begins close that gap between the cushions. Eventually the gap is gone, and depending how much you move, that nice, sensitive area around the anus begins to contact the towel and the little fibers that wick away moisture gently caress. The tabs on my eupho also do this. As I was moving enjoying the contact with my body, I suddenly realized the very subtle sensation of the tabs moving across the towel - catching on each and every fiber. Focusing on that, I now move myself up, down, and side to side maybe a half inch give or take, and experience the most incredible sensations against my prostate. I get the toy to where things feel good and then slowly move back and forth. It's as gentle as someone blowing lightly against my prostate and it just sends me off to incredible places. If I could think straight, I swear I could count each fiber brushing against the toy. 

I say all this as it seems at the beginning of all this prostate stuff,  you have these visions of toys moving in and out, and pressing hard against you. While there is movement, the real pleasure has likely been there the whole time and until you get the chance to really focus and feel, you're just missing it.
