A term that I find useful is “platonic aesthetic attraction”.

It’s a term that I learned through the ace community when I was going through the common bisexual experience of “am I bi though, or am I just asexual?”. It turned out I was bi, but I find the split model of attraction is a useful framework.

Platonic Aesthetic attraction is when you’re able to see someone and go “now that is a beautiful man”, but not experience any attraction in the conventional sense of the word. I personally find it useful because even though I do experience sexual or romantic attraction to people of all genders, that doesn’t mean I experience that for everyone. Sometimes a beautiful person is just a beautiful person.

Edit: got mixed up, and said “Platonic attraction” when I meant “aesthetic attraction”. Thanks to @gerryflap@feddit.nl for the correction
