Hi all. First off I want to thank all of you who provide tips and advice for the less informed.

Here is my situation. Until about 2 months ago both me and my girlfriend were virgins. Since then we have had sex numerous times. And while we have found things that work for us and things we really like, we are both interested and turned on by girl on top positions. However, we have not had any success with them. I have an "average" sized penis and she has a large butt, which makes some things harder for us. Any tips, techniques, or advice you could give me would be greatly appreciated. Thanks a lot.
