How would you react to finding out you were making out with a transsexual?

Even that seems a bridge too far, the girl I was feeling up certainly wasn't molesting me either...but it's just my opinion.

Would it matter to the law if she had or had not told you she was of legal age? I think it would, though primarily in terms of providing mitigation of a charge of rape against you. I haven't looked at the statutes, but I'm pretty sure that consent has to be materially and relevantly informed in order to be consent. If a person is misrepresenting a relevant material fact about themselves, which they arguably are doing in this case, that sounds like a pretty good argument that your right to consent has been violated.
