I agree with the others, I teach the pole sit as "do what is best for you" then expand if they are capable. If you have thicker thighs or narrow or tight hips, crossing the knee can be painful. If you have wide hips or skinny legs with a thigh gap, crossing at the ankles can feel impossible. My male students have only had minor issues with leg hair. It can all be worked around, you just need to be aware. Both my male students are straight...if it matters (They are more into strength moves and less into dancey stuff.) I do not teach the exact same curriculum. Obviously, the basics, safety, and order of progressions are the same, but they advance faster in some ways and slower in others. They are usually awesome with inverts, hand grips and strength moves, where I find my females tend to rock the flex and leg holds. Again, not totally gender dependent. They are both inflexible, but making progress. I teach a mix of moves in the class, so no one feels like they didnt succeed. We will alternate strength moves with flex moves and I offer progressions so when someone does really well with the basic move, they can try adding a harder variation or transition, so I am still teaching the same things. I have been able to integrate both genders in the same classes pretty easily, so let me know any questions, I would love to help!
