Nude & Bi Curious

I am surprised at the number of nudist females on TN that identify as being bisexual or bi-curious. At a guess I would say it's over 50%. Is it a case that Nudist women have less to hide then non-nudist women, and are willing to admit to being bisexual (in which case most non nudist women are also bi-sexual) or is it a case that bisexual women are more likely to be nudist? It's interesting that it does not work this way for nudist men. Not many are willing to admit they are bi curious. Is this because they are not bi-curious or is it that they are less willing to admit it.
