Multi orgasm technic

Interesting stuff

I just got my first multi orgasmic experience. I was laying in bed and stroke my thing. When I was near P.O.N.R I flexed my BC hard and stroked my thing a few times gently and then ORGASM. It was so strong and it lasted in maybe 8-15 seconds, I almost felt that I had ejaculated because I felt it pumped, but I looked down and there was nothing. When the orgasm was almost trapped down I stopped the flex and stroked my dick some times and then BOOM, I flexed it as fast I could and it started to pump once again. I don’t remember how long it continued but maybe little shorter then the first one. Now I was sure that I had ejaculated but there was nothing once again. So I started to stimulate myself again but my erection was all gone so I just relaxed and fall asleep. So for the first time I got a multiple orgasm without a drop of semen. Oh, it felt so great!

** But, why did I lose my erection? I thought you get limp because of the ejaculation, not because of the orgasm.

I really can only orgasm easily when on top of my wife for some reason. I could go all night on bottom if I hold relatively still. That said, when I am on top and about to orgasm, I kegel really hard and push in as hard as I can. My wife seems to love it as I am hard as a brick at that moment and bottoming out a the same time. It may border on the pleasure/pain threshold but she moans when I do it.
