I like starting with cowgirl for a few reasons.
1. I've usually just given a bj so, it's very easy to roll on the condom & just hop on. I like to take charge with my patron in the beginning.
2. This is an easy way for me to orgasm. I mean, I like to get something out of the session too.
So far, I haven't had any complaints and the man usually enjoys watching me orgasm on top of him which then puts him in the mood to flip me over and take the reigns which is wonderful for me.
Hope all that makes sense.
