As a man we learn not to be too emotional with women in the beginning. and women are attracted to men that are mysterious, interesting, charismatic, the man she hasn't had a conversation with. But would sleep with outside of a relationship. And as time goes on eventually she figures out her boyfriend/husband and she has learned his tricks. The man settles down thinking he has his girl on lock. All while there will be new players coming into contact with her with no intent of dating they just want to smash. This happens to every man. Unless you are aware of this and constantly improve (which is possible) do women ultimately get bored of relationships faster because new dick is always more exciting?
