Ok guys,
MMO's... This seems to be much easier for those of us who are uncut (most guys on this board) than cut guys. Personally, I don't need a special technique as referenced in FumingPole's post. I try to make the first shot a slow buildup, and really enjoy it. You shouldn't have to work for it here. Wipe up cum on yourself, and shortly after, resume jerking it, at a more medium pace, but with a loose grip. Sometimes you can ride some of the "aftershock" feelings of the first orgasm, resume stimulation, and get to the next. Sometimes the 2nd orgasm is even more intense than the first. Then, same thing if you want to "Shoot for 3!", but you may need a fast pace. Just seek nonviolent, but pleasureable stimulation. NO DEATH GRIP, as I've heard it can damage your penis.
All these orgasms almost always involve ejaculation, though with each additional orgasm, the volume is decreased. I've gone as high as 7 or 8 in a row (not sure which, as I was getting somewhat aggressive towards the end of that particular masturbation session, was physically getting exhausted, to the point of nearly passing out). I wouldn't recommend regularly going for so many orgasms you nearly pass out. You will be CONSIDERABLY exhausted afterwards.
Regarding pulling back and jerking it: I generally can only do 2, sometimes 3 orgasms while taped back, and further orgasms I will quickly de-tape, grab my foreskin just about a quarter inch on the outer skin side of the ridged band, and continue a somewhat loose grip, and do what feels good.
Intact/natural guys sometimes tell me they can achieve MMO's if they choose to pursue them. Virtually all cut guys the topic has come up with are completely blown away when I tell them I could regularly/easily get MMOs. They say they have yet to experience MMOs, and they wish they could.
Though various techniques/stimulation can get to the first, and sometimes the second orgasm, shooting for 3 (or more) I think probably requires involvement of the ridged band. And guys, I care about ya, and I don't want you to break your dick trying to do this. Personally I'd say it is more common for me to stick with 1-2 orgasms, and call it good. Any more, and you may experience unwanted lack of motivation, tiredness, muscle cramps, inability to concentrate/study for a few hours, or even a whole day.
Another thought in ALL honesty. My intent was to simply share my experience, not in any way to stir up jealousy/envy. I wish everybody would get to experience MMOs if that is their desire. And it IS possible. One cut buddy of mine tried altering his masturbation approach after I told him about experiencing MMOs, and lots of them, and he was able after several several months to finally achieve a second orgasm. Best wishes with all this. Please PLEASE don't get overly aggressive with your MMO attempts, as you could damage nerves and blood vessels in your dick. You only get one.
