Although we have been discussing both gay and straight relationships throughout this chapter, in many ways, gay and lesbian relationships have changed more than heterosexual relationships over the last few decades. First, these relationships came out of the
closet in the 1960s and 1970s, when there was a blossoming of a gay subculture. Then, the advent of AIDS resulted in fewer sexual partners and more long-term, monogamous relationships, especially in the gay community. Although we will discuss many aspects of same-sex relationships in Chapter 11, here we will explore sexuality in these relationships and the advent of same-sex marriages.
