Calonice: "Well, what if we did abstain from, uh, what you say, which heaven forbid: would peace be likelier to come on that account?"
Lysistrata: "Absolutely, by the Two Goddesses. If we sat around at home all made up, and walked past them wearing only our diaphanous underwear, with our pubes all plucked in a neat triangle, and our husbands got hard and hankered to ball us, but we didn't go near them and kept away, they'd sue for peace, and pretty quick, you can count on that!"
Lampito: "Like Menelaus! As soon as he peeked at bare Helen's melons, he threw his sword away, I reckon." (146-156)
Lysistrata's point here is that, even if the war seems necessary, it's actually something the men are choosing to do. However impossible peace seems right now, it would suddenly seem a lot more possible if the men knew that they wouldn't get any more sex until they had put an end to the war. Make love not war indeed.
