If you know how to praise a man, then that is your starting point. Praise how the guy looks, how he makes you feel, if he is funny, intense, mature and so on. Talk about his profession and lifestyle and then praise what you find interesting. If he has friends and family, then knowing about them provided he mentions them can make him attracted to you as well. Men can be as much family oriented as women, but this can vary, so tread this path as per what you observe about the guy you are chatting with.
