I think it will make you bad if you ask her now. It doesn't matter if she show you her underwear, her boobs or wherever. You don't know what really her intentions are...

what about if is one of those funny case where the student will star trouble and tell others you RAPE her? then what you're going to do?
Loose your job, your license and might go to jail? I think you should wait.
Until the School year is over.

Get her in the same situation again and have a break and then tell her
You have been going through an identity crisis and you thing that you may
be gay but your not sure.
Then she will say "what do you mean your are not sure, does this not attract you" as she lays back in the chair and shows a high leg and you take your time and have a long look and tell her you don't know if you would like it but you would like to try with SOME woman SOMETIME soon.

So yes Moe's right..don't tell her you like her, tell her she might repulse you and she will assure you that wont be the case and you
tell her that you don't know and doubt her skills
And make sure you tape her coming on to you 'your the victim here!
Emotionally distraught about your sexsuality! We are sick of been victims!
Let us know how it goes

Don't hesitate. You've done no wrong. Go ahead by taking her out on a date,etc. Then you'll find out what's on her mind but make sure she respects u...i hate all kinds of racism but there are people in this world who just use people like tissue papers. It's obvious that u don't wanna one night fling so take care of yourself first

That's for sure. I'll definitely keep you guys updated as it unfolds.
