Maybe this will help. The esteemed 'dictionary.com' defines the word 'intimate' as...

1) Marked by close acquaintance, association, or familiarity.
2) Relating to or indicative of one's deepest nature: intimate prayers.
3) Essential; innermost: the intimate structure of matter.
4) Marked by informality and privacy: an intimate nightclub.
5) Very personal; private: an intimate letter.
6) Of or involved in a sexual relationship.

I'm not sure that narrows it down much though.
