Oh yeah... Many.
To give some detail: by 'yoga girl' you mean a woman who does yoga regularly and is fit and slim form it or a woman who is a yoga teacher/instructor? I have had many girls who teach yoga as well as many who do it and are quite proficient at it.
I made the comment that Yoga in the west is pretty much gymnastics these days. The girls who do yoga as not too removed from some girls who do cross fit nowadays...
I will remark that women who are dancers (not strippers) such as ballerinas or musical dance performers then to be the most fit and orgasmic in my experience. Yoga girls are also right up there in terms of their sexual responsiveness and fitness.
