What (if there is one) was the moment that made you realize you were Gay/Straight/Asexual?

I realise I love short haired women because of hi hi puffy Amy Yumi, Yumi woke up something in me And I realised I was kinda gay when I found one of my friends and teacher super attractive but I never told them my real feelings, I like men but I prefer women and I like women looking like men
