I think perhaps that some people may percieve male or female energy as intuition?
Let's call it sensory intuition or something to that effect. I think because of the yang energy you exude, even if it's subtle, effects the way you express yourself. Some men have very feminine energy, not gay or transgendered, just have yin energy and vice versa. I have met very feminine women that give off very yang/male energy that have female admirerers even though none considers themself gay or bisexual.
It can get confusing for those that are hung up on sexual identity.
That would be interesting to try. Do you remember where you saw this?
