Аннотация:ABSTRACT Debates over same-sex marriage have reached the main stage of contemporary U.S. politics. The purpose of this essay is to identify and examine how sexual ideologies in U.S. LGBT communities inform and influence relationship construction in general and same-sex marriage in particular. To accomplish this, we first discuss the nature of sexual ideologies. Next, we identify current sexual ideologies in LGBT communities and examine some of their fundamental features and their implications for relationship construction with a focus on same-sex marriage. We conclude with a discussion of what is potentially gained and lost by same-sex matrimonial bonds and explore some of the prospects of relationship construction within LGBT communities in the future.
