I think that is a really tricky question. What really constitutes intimacy? Let's say you were single and went to a bar and had a few drinks and a stranger sat down next to you. Would it be easier for you to imagine yourself, in the course of the evening, telling him the story of your f*cked up FOO and listening to his, having hot sex with him, lending him $100 or helping him out if he vomited up his tequila? If you went out with your own spouse which would be easier for you? IMO achieving intimacy can be pretty easy, maintaining it can be pretty tough. It's pretty easy to get to know somebody. It's more difficult to keep on appreciating them for who they are.
So, that's my answer, I guess. Intimacy is dime a dozen stuff. What I want is appreciation.
