I first started jerking off when I was 16. In my teens and twenties, I had a very powerful orgasm and my cum would shoot out a long way. I can remember lying back in bed and jerking off and when I orgasmed, the cum would fly past my head and stick on the wall. When standing and jerking off, my cum would shoot out about 8 ft, half way across the room. I would shoot 2-3 times a long way and by my 7th or 8th contraction, there was virtually just a dribble.
I was in a picture theatre on night and can remember the night well. It was in the early 70's when a super horny show called Bilitis was showing. It was so sexy, with full nudity and something really to jerk off to. This night I found a private place with noone else in the same row as me. I was jerking off when the schoolgirls were undressing by the lake and I soon shot my wad. The cum flew over the seat in front of me, and hit a woman in the seat 2 rows in front of me. She didnt know what hit her.
Anyway, back to the theme of the story. Over the years, the power of my ejaculation has receded somewhat. I still masturbate a lot but when I come, it just dribbles out. The amount is slightly reduced compared to my former glory days. I was reading one day about a technique called the 'Ice Spurged Special' and tried it. This technique entails getting a bag of ice (crushed or cubed), and as you feel the orgasm intensifying; just before the point of no return; you place this freezing cold pack of ice under your balls, near your rectum.
I have found by doing this, my first squirt is now again quite powerful with the remaining 3-4 squirts still a dribble. Normally these days my cock is at about 75% hardness throughout my wanking, but when using the 'Ice Spurged Special', my cock is at full hardness.
I am sure nearly all males will find this technique most effective, pleasurable and totally safe.
