Having Crush on Teacher is SIN???

not a sin... its very natural

It's not a sin. However, it may not be advisable.

no its a van halen song

no it is not a sin... afterall the teacher is a woman too ,,, human.

There is no 'sin' in having a crush on anyone...it depends on the situation and circumstances as well as what you do with those feelings that determine whether it can be right or wrong.

Only if it's a nun or priest

If she's hot then no

I also lust over my teacher!!

A had er...fantasies of my English teacher during puberty.

A crush doesn’t mean marriage so don’t be pissed off if she brings her significant other into her place of work one day and turn psycho stalker student K ?

Not if its not acted upon.
