I say, why not the girl be more aggressive in her pursuit? I talk to guys about this all the time and they agree that they would really like it if the girl stepped up and be more assertive....they say it's a turn on, secondly, the distance game is what attracts. Girls like a challenge, so if a guy gets all gushy about how he feels about a girl too soon, she will lose interest because the chase is over. Yes it's a guessing game but that is what makes it intriguing and increases the intensity of the attraction. I remember it as being fun.
