How do you call a guy teacher for a date?

Answer 1

If you are a student of his, you shouldn't. He could be dismissed from his job for entering into any relationship with his students. Following that he would have difficulty getting another job as a teacher.

Answer 2

If you're interested in asking a male teacher out on a date, approach him respectfully and politely express your interest. You can simply ask if he would like to go on a date with you, specifying a time and activity of your choice. It's important to remember to be considerate of his professional boundaries, as dating a current teacher/student can potentially cause conflicts of interest.
