Read Ana Forrest's response:
I do not leave students to figure it out. Many poses are intense and painful, and a man may assume that ball-crushing pain is part of the pose when it is not. I tell the men in my class when they need to adjust so it doesn't hurt. For example, I will tell a man in Dhanurasana (Bow Pose) how to put padding under his ribs, or that he may need to back up so his genitals are partially hanging off the mat.
I make it a specific point for both genders that we take care of these parts and avoid pain. So, for example, I tell women how to adjust their breasts if they get in the way during twists.
I address the issue specifically so that these areas—breasts, vagina, penis, testicles—are part of the pose and part of the sacred whole. They need to be treated with respect and care.
