as a male when you have worked your way into being close enough to a female that she shares everything with you as she would a male 'gay friend' but there is absolutely no chance of sex. the no sex clause may be shared or put in the closet by the individual with 'feelings.' if the trust is broken, you are no longer the non gay gay friend.

this is being as deep in the 'friend zone' as humanly possible. you blew it or have now have a great female friend. there is no proof that this does not lead to homosexuality.
