To all my fellow Lesbians and Bi women

So my mom believes whole-heartedly that she knows how lesbians have sex. Despite her being a heterosexual woman. She is
CONVINCED that all Lesbian sex is quote "No different than sex with a man. All lesbians do is use a dildo on each other."
Please you guys tell me she is wrong! There has to be more to sex than that! Is she right or wrong?

Also if you are a straight woman don't answer plz. I'm not talking to you. I'm not interested nor do I care what you have to say on this topic.
