Hey, read your post, and wondered if you had considered you might be on the asexual spectrum. It is massively misunderstood, And yes it's a thing. I usually encourage people to look around themselves and see if they feel it applies , but I would be happy to post a quick set of relevant facts if your interested.
If not I wish you all the best,

and I also agree that high levels of anxiety and related meds can also effect your libido, but if it feels like 'more' than just that then maybe it's worth investigating.
