Everything in our culture makes people, and women in particular, feel that after the age of 40, they're no longer sexually attractive, and this belief gets internalized. But researcher Gina Ogden, in conducting her famed Isis study (a national survey of sexuality and spirituality), found that women in their 60s and 70s were having the best sex of their lives -- people need to understand that the brain is the most important sex organ in the body!
Men and women get into sexual patterns in their teens, 20s and 30s that never change. So in recognizing this, we need to say, "the hardware is going to stay the same, but we can update the software." And you can update the software by trying different things, but mostly by getting to know yourself.
