I have never had an orgasm and it's frustrating to me when I hear of the great pleasure it provides. When I look at myself I look normal since I don't have another female to compare myself to. I think your friend completely misunderstood something. I absolutely guarantee that you do have a hood over your clitoris .
Every woman does.
It helps protect the clitoris. In fact, until a woman is very aroused, direct touching of the clitoris can be quite painful. Until that point, the hood will slide back and forth over the clitoris actually increasing sensation. So not only should you not worry about this, the hood makes it MORE likely that you will have an orgasm. I wouldn't despair, however.
