Sometimes my cock is sore after I'v been edging for more then let's say 5 hours. So it happens that I'm obliged to take a rest to be able to go on the next day.

My longest session was 3 days of about 16 hours each (interrupted two times a day to eat something, and to sleep a couple of hours) I made my spunk go up and down thousands of times, finally my dick was so sore I couldn't hardly touch it any more, and when I released my sperm, it was like dying

I am. When on line, I'm always edging. I love the feeling of my spunk going up and down for hours !

After years of "normal" sex life, I rediscovered MASTURBATION, and thank to internet I became a real freak. I stoped completely making love to be able to masturbate more.
Since I learned about EDGING, masturbation got a new dimention for me.
I do not masturbate any more to ejaculate, but to wallow in the selfish lust of masturbation itself.
I practice use of sperm retention for several days. I don't ejaculate, but throw sprays of seminal fluid or drops od thick juce, I eate while masturbating.
To drain my sperm reservoir, I ejaculate about once a week, after a very long edging session ( to build up big load of sperm)
