Mental health, low libido and asexuality

When I was eighteen I was diagnosed with GAD, social anxiety and panic disorder, along with mild ocd and depression. I've just about managed it ever since, but have never been off medication for long during that time and am now 26. I was in a  relationship before I went on medication at 18 and was pretty into it, but not hugely into sex and was still a virgin. Since then I've had two long term boyfriends and a couple of flings, but never really enjoyed sex all that much - I get off on the idea of it, but not so much doing it.
