    Part II: The Biology & Psychology of Sex

    These lessons dive into the nuts and bolts, the birds and the bees of human sexual intercourse. We start by getting our bearings with an anatomy review, then we study hormones, cycles, and NFP. In hefty lesson three, we get down to the act itself with the sexual response cycle, understanding orgasms, and fertilization. In the longest lesson, we look at sexual development and how sex changes throughout life. In the final lesson, we probe into the mind’s role in sex.
