Wife Has No Desire

Hi all. My wife has opened up to me recently about her sex drive/lack of sexual thinking and we are kind of confused about what to do. She tells me that even since she went through puberty that she doesn’t really have sexual thoughts towards me or anyone for that matter, outside of actually doing the act. Our sex life is great, 2-3 times a week, which is perfect for me. We both have our kinks and specifics that make us finish. But she never “gets in the mood”, so everything kind of feels like maintenence for her. She also says that masturbating has never been a priority for her and that she only does it in cases of extreme boredom. She has no problem getting aroused once sex begins, no problem finishing. I’m not sure of the question that I’m even trying to ask here. Is this something anyone else has experienced? Is it possible that she just is disinterested in sex at all until it begins? It kind of takes a spark out of things for us because she’s never genuinely HORNY. We suspect that she has an attention disorder but she’s never been to the doctor for it. Other than that no known medical or mental health problems.
