Male XYX chromosome

I just can't get it with a male with XYX chromosome. One moment, there's a flock of person getting in the lift. One male, two female. The situation inside the lift is already crowded, so the male is up front, one of the female is behind the male. When they start chatting, immediately I know the male one is either gay or male with female chromosome. So, the female leaning and hugging the this male, with no hesitation. just curious, why female can be so intimate to such male instead of her boyfriend or her husband?
