First, I've never felt the same feeling again as the first orgasm and it was wonderful like I've discovered this new game that I It was awesome and I could play forever without getting bored with it.
I was 12-13. Laying down on my bed with blankes on, jerking off to some porn on TV. Sudenly I felt it was becoming very very good, and I felt like a really warm feeling coming from the tip of my toes climbing throught my thighs until hitting hard this really warm feeling mixed with vibration on my nutsack and coming so hard that my abs muscles contracted and my bladder felt a good tingly sensation..
I remember like it was yesterday, and yet, this was like 14, 15 years ago. Amazing what our memories can retain XD
What about you ?
