I don't know that much about yoga but i work out at the gym regularly with my husband and the workout routines throughout the week naturally leaks over into the bedroom. exercising together usually makes things more sexual. so i'm certain doing yoga together and stretching with each other will all add up as soon as you get to the bedroom
. You just have to be aware to what you are doing at the moment, understanding that, over time, your sex life will get better and better.
