Hi,
this is very inappropriate for your teacher to do. I think you should tell your Father so he could talk to the principal. I'm a Mom of 2 girls and I would never tolerarate a teacher doing that. I glad to you have a strong self esteem and like the way you are. Too many times, as women we are made to feel in adequate with our looks.
If you do wish to explore that more girly side would there be any other woman relative or friend who could advise you. But, if you're happy with yourself then that's okay too. Don't let that teacher get you down and get your principal invoved.
Work on building your self esteem by loving yourself the way you are and thinking positively. Eat healthy, exercise moderately and surround yourself with good people. Concentrate on getting good grades and building a good future.
That teacher should be ashamed of His/herself. That teacher should be teaching, not commenting on how he/she thinks you should look.
Keep be strong - you go girl!
