Question about masturbation and PC.

I want to know is it danger to squeeze the prostate (by holding), then stroke my private one time (by masturbating)?

It is like the squeeze and flex technique from this site http://www.erec tionstrengtheni … ueeze_flex.html

But the only differences is, it is pure erection. Is it danger ?

It may possibly cause occasional retrograde ejaculation if you try to squeeze very hard while ejaculating, but it is not dangerous. Retrograde ejaculation - Wikipedia

I wonder if I suffer from this, reason being is my "finishes" are nowhere near as satisfying as they used to be.

Thanks for telling me this. I like feel I’m possibly on the way of having this.

One way to determine if you are experiencing a retrograde ejaculation is to see if your urine is cloudy after you ejaculate. Don’t go pee right after you ejaculate, because it’s almost always a little bubbly/cloudy for me right afterwards, but if you pee about 15-20 minutes later and it’s cloudy or bubbly then you probably have experienced a retrograde ejaculation.

The reason I know this is because of a multiple-orgasm technique that I have heard referred to as "the lion" , which can easily cause a retrograde ejaculation if done incorrectly. While practicing it, I did it incorrectly, and I saw obvious results when I urinated about 15 minutes later. If you already think you are experiencing retrograde ejaculations, I obviously wouldn’t recommend trying "the lion", I just wanted to explain how I know this.
