When riding isn't it suppose to be common knowledge to use full range of motion? Full range in terms of going all the way to the balls....I figure I would ask because its becoming harder to find women who are true riders. Most want doggie which I also enjoy but riding is the ultimate.

Everyone has their own "style" or method.
I find each situation to be unique.  There are no identical anatomies, so it is never the same.  Then factor in chemistry, personality, etc.  I could go on all day with a list of variables.  
I guess it just depends IMHO

That's the kinda chick you want. Hard to find...BUT worth waiting/fighting for. SOLID & down. Plus smokin hot? Yesss
 hiiii btw. . Check out this video of my fav girl ever... damn near perfect "ride or die" (my opinion)  & I get it xo, Devin D
