Helping you with phimosis, frenulum breve, tight foreskin, and other male health issues.
If you experience pain while stretching, you are stretching too hard. You only want to be stretching enough to actually feel the sensation of skin being stretched.
Another way to describe it is that you only want to stretch your foreskin as hard as you might stretch your arms when you’re yawning. It’s not hard enough to cause pain, but it’s hard enough to create tension.
