Just took an educated guess hun... This is a cross dresser site, she said she'd been caught a couple of times, so I assumed that she meant that she got caught cross dressing.... The OP didn't contradict me, and even commented that I made a good point.
As for a lesbian presenting as a female...Why would someone assume that she was gay if she is a woman presenting as a woman? This pretty much sounded like a .. why can a woman wear men's attire and get away with it, but if man wears girl things, the assumption is that he is gay. I could be wrong, but... having seen a number of these type threads I am pretty comfortable with what I stated, and stand by it.
