Tips & Tricks for Being on Top

I am a plus-sized woman who is not very confident with taking charge while having sex with men. I would love to see a full-bodied female performed show all the positions that work for a bigger body to take charge and make mind-blowing sex for him AND HER. To be honest, I am not sure if this would be best as a how to instructional video (similar to the Tips & Tricks for Sucking Dicks) or just a sexy film that focuses on the above confession.
