Butch and femme are terms to describe different ways people present themselves in relationships.
Butch means a woman who dresses and acts in a more traditionally masculine way. This might mean wearing men's clothing, having a short haircut, and being more assertive or dominant in relationships.
Femme means a woman who dresses and acts in a more traditionally feminine way. This might mean wearing dresses or makeup, having long hair, and being more nurturing or submissive in relationships.
Some people might identify strongly as one or the other, while others might feel more comfortable mixing elements of both styles.
It's important to remember that these terms are just one way of describing relationship dynamics and don't define a person's entire identity. It's also important to be respectful of everyone's unique expression of gender and not make assumptions about how someone identifies based on their appearance.
