Well, there is a difference. The situation you described was that men were chatting you up in order to get sex. That is simply a guy going out on the prowl for some fresh meat. It's typical behaviour in social settings.
In order to compare to the type of woman I was mentioning, I think the guy would have to be clueless, desperate for attention, love and a relationship. Someone who needs someone else to be with him in order to bolster his non-existent self esteem. The situation you described were just cheap pick up attempts, not neediness and desperation as I was previously describing it.
