At regular yoga, I prefer to practice in the front row, because seeing a bunch of bodies in front of me always makes me feel crowded and claustrophobic, so I had no problem nakedly sauntering up to a space sandwiched between two dudes in the front row at Naked Yoga.
Here are the things that were awesome about it:
Soft lighting! Both the lobby area where you strip to store your belongings, and the studio itself are pretty dimly lit, so it’s really hard to see anyone’s bits in hi-def, even if you’re looking for them. I dare say you could even get away with not trimming your tampon string and nobody would notice it.
