Is it normal to have a crush on your teacher?
Mostly.Normal for most people
Yes, having a crush on a teacher is pretty common, especially when you admire them or spend a lot of time around them. The feeling is okay; keeping appropriate boundaries matters.
Teachers can seem especially appealing because they’re confident, supportive, or good at what they do. A crush can happen without meaning you need to act on it, and it often fades with time or distance.
Enjoy the harmless butterflies, but keep things respectful and don’t pursue a romantic or sexual relationship while they’re your teacher. If you’re under 18, the adult teacher is responsible for maintaining that boundary; if they encourage anything romantic or secretive, tell a trusted adult.
