Question: "What does the Bible say about being a lesbian? Does the Bible mention lesbianism?"
Answer: Some are under the assumption that, while the Bible condemns gay sex between men, it nowhere condemns being a lesbian/lesbianism. Leviticus 18:22 and 20:13 mention men having sex with other men, but say nothing of women having sex with other women. In the Sodom and Gomorrah account in Genesis 19, the men of the cities wanted to gang rape other men. First Corinthians 6:9 mentions effeminate men, very likely referring to homosexuals, but does not mention lesbians. So, does the Bible in fact condemn male homosexuality, but not lesbianism?
Romans 1:26-27 puts this invalid assumption to rest: “Because of this, God gave them over to shameful lusts. Even their women exchanged natural relations for unnatural ones. In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed indecent acts with other men, and received in themselves the due penalty for their perversion.” Clearly, this passage puts lesbianism on equal ground with male homosexuality. Lesbianism is described as women exchanging natural relations (with men) for unnatural relations (with women). According to the Bible, being a lesbian is just as sinful as being a homosexual male.
There’s an implication in Romans 1:26 that lesbianism is even worse than male homosexuality. Notice the phrase “even their women.” The text seems to suggest that it is more common for men to engage in sexual depravity, and when women begin to do it, that is a sign things are getting really bad. Men usually have much stronger sex drives than women, and so are more prone to sexual deviancy. When women commit unnatural sexual acts, then the degree of immorality has truly become shameful. Lesbianism is evidence of people being given over to “the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another” (Romans 1:24).
