Stretching leads to a less rigid penis

This is something that I heard years ago (I can’t even remember where I heard it anymore), but the idea was that stretching the penis would eventually lengthen the suspensory ligament, and since the suspensory ligament aids in supporting and keeping the penis rigid when it is erect, lengthening it would lead to a less rigid penis. Is there any truth to this?

It looks that different people report different effects. See this poll about the subject.

And you can find more threads about this subject by searching for “erection stretching”.

Having 9 out of 10 say it has either had little negative effect on erection angle, no effect or a positive effect is pretty encouraging.
