I’m a male, having a doubt about Istibra:

During 1st step, I must press 3times from a little distance after anus to where? Should I press till the back of testis or all way up the testis till the start of penis(front of testis). What I mean is should the scrotum area be exempted from pressing?

Yes, it is enough press from near the anus to the beginning of the penis, without the scrotum
