Wandering, that first time experience note you just wrote is pretty indicative of how you have to get it to go if you ever want o get the chick to do it again. Good advice for those guys out there who are looking to go for try number 1.
As far as the guys who want it all the time, it's not that I don't see the appeal but I don't think it's all that much better than some dirrrrrrrty (read: awesome, not actually dirty, that's gross) doggy style. Then again, it is super tight and sometimes when you're drunk, it's just what you need to get you over the edge. Always worth trying ladies
