My boyfriend always wants me to go on top. I can't do it? I sometimes go on top and get myself into a frog position with me feet on the bed, knees bent and hands on his stomach. But my legs get tired so quickly. Other than that I can just rock up and down but that's so slow. I feel like I'm bad in bed because he's always doing the work but I honestly don't understand what people do and how they keep going!!
