I had this when everytime I do stretching.
I felt like the ligament become hard and make my penis stiff and tight.
But it will go away by 1-2 days
It’s been like this for months now, and 3 weeks I’ve stopped masturbating.
Also, it’s not psychological. Why would my dick just go down halfway through masturbating when I’m standing - but not when I’m sitting down. And why do I not get full boners in the morning.
And why, when I stand up, does my dick go flaccid-hard.
That is NOT Psycholgical.
