Loss of libido after switching from finasteride to dutasteride

[longseasons]

Hello, I am a 29 year old male. I responded well to finasteride for 5 years (from 2013 to 2018). In 2018 due to hair greed and concern that I was slowly losing ground (in hindsight was probably overly paranoid, eughhh), and after looking at the very similar safety profiles of fin and dut- I switched to dutasteride.
Everything was fine until about 10 months in (July 2019) when I noticed I wasn't actually craving sex anymore or feeling any real sexual attraction. This was pretty depressing. I dropped dutasteride almost immediately and have remained on fin since in the hope some libido would return, but about 7 months later and I still feel no actual primal urge. It's like something is ****ed on a neurological level.
It's worth noting that my penis is still fully functional- I even wake up with morning wood and still masturbate just for the hell and fun of it, though I don't feel like I'm 'scratching an itch' like before and it's certainly not the same experience it was before. Sex too, is perfectly doable and reasonably enjoyable at times but not the same satisfying experience it once was. Orgasms still feel the same, ejaculate volume and consistency is the same. I do have though a pretty persistent mild, tingly, 'pins and needles' like feeling in my groin area.
Most of the time in the last 7 months I haven't been overly depressed or bothered about this as physically I am ok but when I actually think about it I realise it's kind of screwed up and would like to feel actual desire again. Any advice on how to maybe get something back? I realise now switching to dut was a mistake but what can you do.
I'm going to ween off finasteride slowly and see if that shakes thing back into shape, with a view to get back on it again once I've wiped the slate clean. I've also ordered some tribulus as I hear that's good for libido. Anything else I can try?
