I have a question. I am a small female and have trouble having sex on top. All goes well, but then I can't get the leverage to move up and down or something. Anybody heard of this before or have any suggestions? I've tried pillows under my knees, but that hasn't really helped. I feel like this shouldn't be so difficult, and from what I hear woman on top sex is something I don't want to miss. I appreciate all suggestions.
