Mismatch

So, the way I feel about this person (Awesome Hair Guy is the nickname I’ve used for him before, I think)  is a way I’d describe as finding him attractive in a sexual way.
But there aren’t actually any sexual acts that I can imagine wanting to do with him.
So like…
Is this fantasy-interests vs real-life interests?
Is this sex vs non-sexual kinky things?
Something else?
Or not actually sexual attraction?
