A friend of mine from a while back was an Ace woman who was in a steady relationship. She was very open about her orientation and would answer questions if you asked her in good faith. I don’t think they scheduled their sex, but she much like you was interested in making sure her partner was satisfied. I used to joke that I knew Ace people who had more sex than me because of her, but the moral of the story here is it’s definitely a manageable thing with the right partner.
