If a guy is big then I have to start out on my back. The top must know what he is doing to you, and a good top will read your face and sense any discomfort. Once a top is in and has worked me over/loosened me up, then I can take it anyway he wants.
Missionary is the only way I could take anything over 7 back in the days when I bottomed. I'm super tight, though... so I'd have to start with my fingers, then just sit on it until my muscles stopped freaking out. Bottoming was such an ordeal, that's why I nixed it! :tongue:
