It's officially ok for you to do Yoga now. So get your butt to class because downward dog is good for you! Just because you can't touch your feet doesn't mean you can't do yoga. Get over yourself and grab a strap. Have fun, don't clench your teeth. You will be in headstand in no time! Touching your toes? That will take practice -often, consistently, for a long time and with earnestness.
Namaste to all the boys and men I teach!
