Aro-ace crush

I have a crush on one of the guys in the gay men’s chorus. 

Admittedly, I hardly know this person. But there have been more direct interactions between us than with other choir members and there seems seems to be a mutual liking, although I don’t exactly know of what sort on their part. 

I hardly know him and yet I instinctively feel a very intense draw towards them that in some way is beyond, or different from, platonic while still not being romantic or sexual. 

Why do I feel this way? 

Because they’re a queer, AMAB, gender-bending, slightly-more-masculine-leaning person and that’s “my type” (or “one of my types”)? Or because he reminds me of my European (gender)queer ex-lover, who was a “similar type”? Or because they’ve shown some interest, or at least friendly affection, towards me, and maybe I’m somewhat recipro-romantic/recipro-sexual? 

The way in which I “like” them or am “drawn to him” is beyond or different from platonic for me in the sense that I’m not just curious to get to know them better and/or just hang out with him; I also want to touch/hug them and want him to touch/hug me a lot, too; I would like to cuddle with them and I can even feel the desire to sleep or lay in bed with them and explore what might happen, including potentially sex. But not in a sense that I feel sexual attraction towards him (like I did for the guy at the climbing gym or my fuck-buddy in grad school). The sex would rather be from a sense of curiosity mixed with an instinctive feeling of being safe with him and a desire to get close/intimate with them. And it partly also might have to do with my desire & need not only for physical closeness/touch but to actually be held and/or be liked as a genderqueer boy by another genderqueer boy — with all the affirming validations that would entail for me.
