Is this the Kundalini force?!

Is this the Kundalini force?

I have this unique ability to make a very pleasant bodily sensation. It is almost orgasmic, it feels like a sensation of free-fall. I am not sure if I am stimulating a muscle- inducing the feeling seems akin to kinetic volition.

* The sensation feels as if it originates at the end of my spine/perineum area, or deep in my stomach.

* The sensation radiates outward but mostly upward to my head.

* When it shuts off (when I stop causing it), I feel the aftershock wave of the sensation ceasing.

* If I cause it to happen for a long time, I will temporarily remain in a state of calm, peace and elated arousal.

1. So is this the kundalini force, or is it something else?

2. Is it harmful to do? (Am I losing something by creating the peace)

I also know it's not addictive because I don't sit around doing it all day. I'm too lazy. But if it's not bad I probably should be doing it.

I forgot to mention, I'm using only my mind/thoughts to cause this.

It sounds like Kundalini to me.
The Root chakra (at the base of the spine) is considered the doorway to Kundalini energy (which originates in the earth), and when it flows freely it flows up through the body to the head (crown chakra).
Some people spend years finding a way to do this, so consider yourself fortunate.
Over time, this energy is supposed to cleanse the entire body and energy channels - leading to physical, emotional, and spiritual health and vitality.

There are all kinds of books and classes on Kundalini, it may be worthwhile doing some research for yourself to learn more and understand it thoroughly.
