Ignore em! Sounds like you got one person's opinion as opposed to the college's viewpoint.

It is actually more the rule than not, especially for high school kids, to be bi-curious or what they call bi-sexual. In reality, they just don't know yet what they are.

Now, please don't think for a minute that I'm inferring that you don't know that you're bisexual. I don't want there to be any confusion between us over that point.
Take care,
