No personal experience of the oestrogen-based sort to share, but wondered if low-dose testosterone might be something to explore? From what I can work out from the internet, it might be a bit of a long shot, as it only seems to be indicated if oestrogen HRT hasn't worked in certain ways - and one of those ways seems to be "lack of sexual desire", which isn't entirely helpful if you're happily asexual. On the other hand, when you said "genderless goblin", low-dose T is immediately what I thought of.

My own experience of T in higher doses is of mood stabilisation almost to a fault: mostly it's brilliant but there have been one or two occasions when I have felt It would be extremely nice to be able to have a little cry now and I just couldn't. Very weird for someone who was always told in childhood they cried too much and too easily and learned all the tear-suppression strategies.
