I found it!

I was a late bloomer in regards to anal play and didn't start to finger and explore my ass cavity until well past my teens. It took a while to find my prostate but once I had my finger on it I was surprised by how good it felt; I could have creamed myself right there and then, even without touching my dick!!

I continued to casually experiment with this while wanking and jerking myself and realized sometimes all needed was to slip the tip of my finger into my ass as I approach orgasm and that would be enough to boost the intensity of the climax, making me pump out nice big warm spurts of cum!!

I must have found my G-spot cuz if I came any harder I would have passed out from all the extreme orgasms I was having! I mean I'm not trying to brag about it as I'm sure most people have achieved this (I hope!)

Years later I decided to step it up a bit and get a vibrating prostate butt plug and let me tell you they cum highly recommended! I was able to edge my climax to prolong the ejaculation. Boy what a mess I was making. My arousal was so heightened that sometimes I would get a hard-on at a non appropriate time and even get so turned on out of nowhere having mini orgasms whilst driving or exercising..

Who says only girls can have multiple orgasms! :)
