Penis root question

It’s been difficult to keep an erection during the 10 min penis root exercise. I stay semi-hard, but not really fully erect. Is the exercise still working and worth it? Also, should I vary the pressure I’m massaging with? Thanks!

Had the same issues but just think of a fantasy and forget about the massaging. Focus fully on the fantasy and I came in about 9 minutes

Ok, thanks for the suggestion. I can’t imagine climaxing with this exercise but maybe I’ll get there eventually.

What is a penis root massage?
