This is an article explaining (graphically!) how a lesbian should have sex with a person with a penis. So a man.

This is part of a series called Lesbian Sex 101: "Employment of the term “lesbian sex” in this post uses “lesbian” as an adjective to describe sex between two women or people who identify with that experience, regardless of the sexual orientation of the two people involved."
So basically, emphatically not lesbian sex, given that lesbian sex is sex between two biological women who don't have penises.
