I’m not sure entirely how to answer your question but I would like to say that when you’re really not in the mood a fun way to get there would be to start with a massage, no pressure just touching and experiencing a intimate connection, if that doesn’t lead to sex you still have shared an intimate moment with each other, and if it does it’s a good way to get really warmed up and relaxed. Another thing would be finding other ways to be “sexy”, talking dirty over text or sending suggestive photos can be a huge turn on for your partner and you can just be sending a couple photos here and there while watching Netflix. I would also suggest talking about your fantasies the things that do sound hot to you and sharing that with them so if the mood does come up they can make sure you’re having an experience and not playing the part, and lastly find someone patient and trusting because you should never be pressured into sex the right partner will be your partner in all things
