Girls who put out are tramps. Girls who don't are ladies.
This is, however, a rather archaic usage of the word.
Should one of you boys happen upon a girl who doesn't put out,
do not jump to the conclusion that you have found a lady.
What you have probably found is a Lesbian.
~ Fran Lebowitz
Every woman I have ever loved has left her print upon me,
where I loved some invaluable piece of myself apart from me--
so different that I had to stretch and grow in order to recognize her.
And in that growing, we came to separation, that place where work begins.
~ Audre Lorde
