it feels a bit boring to say, but… i've never had sex, and i don't want to. if sexual attraction really is feeling desire to be sexual with someone, then i've never felt it.
my journey of discovery was also pretty uneventful, as a teen i realized that people my age were pretty much all interested in sexual acts, and i thought, "hey, shouldn't i be interested in that too? shouldn't i feel sexual attraction too?" and then i remembered asexuality existed, looked it up, and went "yep that sounds like me!"
i have felt romantic attraction tho, once, and it was a very weird feeling that i can't really describe… i think i'm on the aromantic spectrum as well but i'm way less sure of that than of my asexuality
sorry if that's a bit of a boring answer, i guess my sexuality is just "nope" 😅
