Involuntary body shaking and waves of pleasure. Getting close to super o after years of trying.

I had given up before as I never got any pleasure from prostate/aneros play, but one day it clicked. After years of edging, it gave me really good stamina and control over my PC muscle which gave me control over the same muscles involved with full body orgasms. I always knew how to squeeze my glutes and lower body muscles to cause sensations, but I never associated it with sexual pleasure. Most people have felt these sensations in some capacity before but they were too mild to notice. With practice, you are able to amplify these sensations.

I do a aless warm up, insert device, start “seesawing” my PC and sphincter muscles with a rolling motion. Blood rushes to lower body, legs start shaking and I start to get chills in my spine and waves of pleasure in my genitals/erogenous zones. The shaking gets more intense and spreads all over. Feels like a mild electricity pulsating. I redirect the shaking towards my lower body and try to stop the involuntary shaking, which leads to auto thrusting. Breathing becomes shuttered, and the contractions become more pronounced. Heart starts pounding.

Its like like surfing, finding a wave, and riding that wave as long as you can. Over time you are able to ride bigger waves.

I have nerve damage from circumcision as a child and while standard ejaculatory sex feels good, its never been a crazy mind blowing thing for me(also dont want kids). I also dont like how it drains you of your sexual energy and makes you lethargic. Full body/tantric/prostate play doesnt do that and it makes me feel energetic and euphoric, while ejaculating just makes me want to sleep and shuts off any sexual desire.
