The problem with sex in BG3 is that it was added for the purpose of adding sex to BG3. It has no narrative connection, no cathartic relationship to any of the plot, and is nothing more than digital masturbation. It's a reward for choosing a dialogue path.
One of the oldest axioms in art is "if it doesn't add anything, take it out."
You probably haven't played the game enough then. Minthara, Gale and Astarion sex scenes are directly linked with the plot.
