A Bisexual Lesbian (or Bi-Lesbian for short) is someone who is both bisexual and a lesbian. There are many reasons why someone may choose to use both labels, including but not exclusively: Being a bisexual homoromantic woman or woman-aligned person, using the SAM, having a heavy lean in attraction towards women, reclamation of the term since the label used to be inclusive of bisexuals, and so on. There has been a wide variety of sources and information published on bisexual lesbians in recent months, most notably from the Tumblr user @bi-lesbian.[1]
Controversy
Many people see the label as “contradicting” or both homophobic and biphobic. Many feel that Lesbian isn’t an umbrella term, and that treating it like such hurts the community and makes it easier for cishet men to prey on Lesbians. Ultimately, however, this term isn't a new one, with much of it's history documented on a sources page created by an anonymous user.[2] The term lesbian had been an inclusive one since it's creation up until the seventies, when political lesbianism and lesbian separatism grew in popularity.
