So uke has crush on another man? I’m confused

Uke was being very persistant about going all the way. Seme asked what man he was into then because he realized if he's that interested in getting penetrated during a 'lesson' it was because he found some romantic interest in a man instead of a woman. So Seme started feeling annoyed/jealous and blurted out that question of what man he was into. Uke obviously is aware he's growing to like Seme more and more but he can't just say he's into the seme so he said he was just curious.

Thank you so much for explaining
