Help!! Would this be wrong/illegal?

It could lose him his job ... and his marriage. So yes, by conventional moral standards, it IS wrong. However, you seem to act like a sl�t in the classroom, so by your own moral standards, it is normal, decent behaviour. Your only concern is any media publicity which could result, but maybe that is not a consideration for you either. After all, we already know that you are a 17 year old Polish girl, living in Northern Ireland, with the username Alli Dames. You are 5'7" in height, you are tanned, you have light brown hair and green eyes, and your bust size is 38C. You take Business Studies with a married male teacher who is about 29 or 30 years of age, and who looks like Adam Gontier. That narrows it down a little.
