How is the experience different than non-naked yoga? At that point it was too late to back out. However, the class really woke something in me and I was hooked. It is magical having an hour alone with your body, without even your clothes to distract you. For there to be a non-sexualized space where gay and bisexual men are naked is incredibly liberating and self-actualizing.
How do I prepare for yoga class? Wear clothing that is easy to get out of and into again. Each student gets a pigeon hole to stow his clothes and shoes but space is limited so consider changing out of your work clothes and into clothing that is more space-saving, like what you would usually wear to the gym. Take a Shower Before Class Your teacher and fellow students will appreciate this gesture. After you shower, apply deodorant, but avoid wearing strong fragrances to class.
Men who have taken coed yoga classes may well have been greatly outnumbered by women, who are generally more flexible and better at yoga than men. Also, like most anonymous classes, commercial coed yoga classes tend to cater to the majority, so the less flexible and less active participants — most often the men — can easily feel left out. Just like women-only classes, men-only classes can better focus on a homogeneous group of participants whose abilities are generally more similar. The atmosphere of a men-only class therefore tends to be non-judgmental, non-threatening and non-competitive. The benefits may be small or great, but there will be benefits, no matter where participants start.
That's not necessary at all. This rarely happens, and if it does, it's nothing to be embarrassed about and will pass quickly. You will have so much to concentrate on in order to achieve and maintain your postures and your breathing that this probably won't be a issue. If it does happen, it's ok--don't worry about it. Erections are not a problem at all—they are part of what makes us men.
