Another theme is war or violence. The women rebel against the men and get together (from both sides) to plan how to end the war their men are fighting. The women withhold sex on both sides of the war in order to end the fighting. So, ultimately, the men are fighting against one another and the women are uniting to fight against the men to end the war/violence. Very ironic, and extremely amusing.
One of the themes in Lysistrata is obedience. The women are no longer willing to be subservient to the men. This shocks the men when the women are vocal about their discontent, and willing to fight about it if necessary. They are giving up the usual, traditional roles of wife and mother to fight.
Another theme is that of sex. The women are using sex as a weapon to fight the men. They band together and withhold sex in an attempt to weaken the men and have them give in. It is one of the few true weapons that these women have in their arsenal.
Sorry for the first answer (IK/) I did'nt mean that .But I think there is another theme which is librety that all the women seek at two level .First,they want to become free from men's authority and their point of view toward them.Second,they want to get red of war that destroyed their lives .
