My personal favorite is doggie style. I also like having my hair pulled while in this position. But like the first post said it can change on any given day, with any mood

There are many positions possible (see the Kama Sutra) simply because there is no one answer to your question. We can enjoy enjoy different positions and each of us has favorites and some that do not work for us. Changes with mood and age.

Look around the site; there are good ideas.

My girlfriend likes missionary the best. We have tried her on top and that. She wont try any others though.
