    This is a very sensitive issue, but frankly men will 
    always try to hit on women.

I don't usually take part in these conversations because I don't think I have much to add. However, a comment like this doesn't do anything constructive. The problem here wasn't even "men hitting on women". The problem is men hitting on women in an inappropriate context.

To your credit you go on to touch on this a little by sort of obliquely asking the question "what contexts would be okay?" But you completely ignore the truly easy first step. Which would be: Don't assume you know what contexts are okay until you've gotten to know the other person a little better than a few drinks and a couple conversations.

There is no "framework" for this other than taking the time to learn about the other person before you make any kind of move in the romantic/sexual arena.

Let's take your example:

    telling a woman she is gorgeous without asking for 
    anything in return is okay.

How do you know that is okay? You actually can't. Not until you've gotten to know them first. You can't be sensitive to what how another person will feel about a comment like that without gathering some background information first.

Your whole proposal starts with a flawed assumption that there is such a thing as a one size fits all framework for men and women to work together and date.
