First visit to the dermatologist?

Just wondering what happens when you go there. I have a family history of skin cancer so that's why I'm going. Will it take long? What parts of my body will he check if I don't have any specific areas of concern? How much clothing comes off? I am a female with a male doctor and I am a little unsure about that, because all my doctors have been female. Please answer with as much detail as possible about the exam.
