Have you ever tried to count the number of pumping contractions you have when you orgasm and ejaculate? Does it vary much for you or is it typically always about the same amount?
How many of your contractions are typically what you?d say are those most powerful and pleasurable ones, versus those that come towards the end when the intensity is dropping off?
Does anyone have ejaculatory contractions that are equally as pleasurable all the way through an orgasm?
It seems to me that most of us probably experience the most intense pleasure with the first 4-7 or so contractions. Long, deep pulsing is the best with plentiful semen emission. The contractions then might speed up but be less intense as the orgasm subsides.
Any strategies/techniques fir increasing the number of spasms?

With prostate massage you can achieve multiple orgasms with no down time.

As boy, I?d say I produced up to ten pulses. A good jet of semen with the first two, diminishing thereafter. Now, at 77 there are less than five pulses, none of which could be termed a spurt. Orgasm is still strong - thankfully!

I usually have 6-7 contraction that will shoot out cum. As far as dry contractions unsure.

I finished up a Fri night/Sat edge session late Saturday PM. Longest edge session I've gotten through. Usually, when I try that is develop a case of blue balls after I edge three times, or so, up the the Point of No Return and then back off. This session, each time, after edging while camming and surfing porn for an hour or two, I finished a around of edging I put my dong and nuts in a nut sack...sort of like a jock strap..to give my nuts some lift and extra support. It worked! I went more than five rounds! My nuts got really hard (due to jizz being stored in the vesicles) and started to swell the last time around, but I could even get my snap cockring on (often the nuts get to tender for me to do that). By the third round I was really leaky pre (which I don't do often) and had a few "pressure release drools, where prostate fluid flowed out without an orgasm. Especially amazing since I had not squirted in over a week. Well, bud, when I finally shot my cream it was the most mind blowing orgasm I think I have ever had! I don't recall it fully because I was in so deep, but my eyes rolled back and my whole body went through five or six whole-body INTENSE spasms as my juice squirted out. I lost count of the total number of contractions--these spasms were on another level! I'm definitely adding that ball sack to my arsenal of bate accessories. i can't wait to get another long stretch of time.

4-5 seems a reasonable number as i recall.

In my first decades of masturbating I trained my cock to climax as I wished, with voluntary control of when and how my orgasm throbs occurred. Happy to discuss this with other masturbators.
