Interesting responses...
@BigAl9 comes closer to my feelings BUT, I would think that, although the actual orgasm and the leading up to must be the the same for everyone, the scenarios and how we interpret it varies. I have been one who - sadly - try to evaluate most of my orgasms. I have been too lazy afterwards to write about it so I will try to remember now the feelings. As a side note, I have only been able to completely disconnect like 4 times in my short sexual life and the emotions have ran so high that I had feared death.
So, how do I describe an orgasm:
It feels like there are thousands of sensors in your penis - most in my tip - and sensors in the groin area. All of those sensors are super activated during this time, overloaded with information that it becomes impossible to track, like when being tickled a lot. As I'm reaching closer and closer, it's like if there are thousand of tiny hands massaging me from every corner of my body in the direction of my penis and flowing out of it. Feels like a comfortable tickle, like ice cream or a very yummy food, together with the feeling of release when peeing after the urge. But then there's more. It feels like your pelvis is levitating, hovering, like being held up just by your penis and all the weight of your body rests on the tip but it doesn't bother, instead it feels as if the weight is also giving you pleasure so you pump harder and harder and it gets a lot nicer as you get closer to the climax. Then at some point its like if you reach cruising altitude, over the clouds at Flight Level 1000+ or out of this world... like the classical music example.... like a long held beautiful note in a church choir... and you are hovering for a tiny few seconds.
During these tiny few seconds, the mind shuts down and there's only your body and the penis. In my view, it is in this moment when I am most vulnerable. It is the moment of ecstasy and of the I love you's (and etc). It's the moment when you say yes to anything and everything is beautiful. The trust may slow down here a bit and you even get a slight amount of fear, like if the end is coming. But it also feels like joy... like when you laugh out loud crazy... and extreme happiness, but also extreme power, like if you're Thor and on top of the world. Like you're the greatest, most powerful thing in the world.
And right before cumming, reason is no more. Involuntarily, you pump, trust, move harder and harder while all of the previous described emotions get amplified. Then it's like if a nuclear reactor gear starts running, out of control - this is all on fractions of seconds - and out of a sudden, all the power of the world gets released out of the penis in what may feel like a nuclear explosion of uncontrollable pleasure & emotions. You even get that feeling of fireworks... the low bass you feel in your heart when you hear it pop... So much, that I don't think there is a way to stop it - the famous point of no return. Each emotion gets amplified by the pulses on your penis as it is pushing cum out. The first usually the greatest but sometimes even the third gets huge. And at that moment, and for a few seconds, nothing exists. The world could end and you wouldn't even notice. And the rush of blood and electrical currents going like crazy all over your body, out of your fingertips and even hair, teeth... its so powerful that it renders you useless and you have to stop moving.
Since the question was about the Orgasm... there it is. Not sure if I should keep writing about the aftermath. I will try to record more data in my next one.
