I am 17 and I don't really know very much about sex or anatomy, even though I am supposed to be studying biology. My worry is I don't seem to have a clitoris. Is this possible, doc?

Almost impossible. However, many young people, including a lot of men, have great difficulty in finding the clitoris. If you make an appointment with your local Family Planning Clinic, one of the friendly nurses or doctors there will show you where it is.
