Johns Hopkins University has issued an LGTBQ glossary in which it defines a lesbian as “a non-man attracted to non-men.”
The glossary explains that “while past definitions refer to ‘lesbian’ as a woman who is . . . attracted to other women, this updated definition includes non-binary people who may also identify with the label.” A gay man, however, is still defined as “a man who is . . . attracted to other men, or who identifies as a member of the gay community.”
