Lesbians what do you love about women?

My cousin is a lesbian. She is 24 and married. I have been focused on them looking at their relationship. Even though I am bisexual. I think I can look up to the way they are emotional with each other, for me to find a girl. My cousin and her wife are huge anime fans like me, my cousin is the perverted one who makes the jokes, her wife seems to be the submissive one. They are also very open about their sexuality. Which is funny because women I hear are not open about sexuality as opposed to men. But my cousin says she just likes the female package as a whole. She is not sexually interested in men. She views them as good friends. Im 15 and she used to baby sit me a lot. She came out at age 14 with her parents totally approving it. So I wanna ask what lesbians like about women and if their story relates to my cousins.
