Summary
Unlike extensive research conducted on courtship, foreplay, and intercourse, what happens after ejaculation is one of the most neglected dimensions of human sexual behavior. As described in this chapter, postejaculatory adaptations have important and diverse implications for such things as penis hypersensitivity, the refractory period, female infidelity, sperm competition, semen displacement, self-semen displacement, spousal rape, the risk of transmitting sexually transmitted diseases for uncircumcised men, and the incidence of nonpaternity. This chapter also outlines ways to test the Bruce effect in human females and provides a novel explanation for the absence of the Coolidge effect in women.
