I always leave a 'muff' at the top, and I used to shave the bottom part (labia). I thought it looked neater and nicer this way, and also helped me with anxiety about getting oral. (the thought of hubby getting hair stuck in his teeth is not a pleasant one)

But recently I've stopped shaving the lower part, because I got to wondering if it was reducing my sensitivity. I've been having problems with feeling pleasure when being touched, so I figured I'd give not shaving a try, so now I just trim. We'll see how it works out.
