Affirmative consent

32 Come, let us make our father drink wine, and we will lie with him, that we may preserve offspring from our father.” 33 So they made their father drink wine that night. And the firstborn went in and lay with her father. He did not know when she lay down or when she arose.

34 The next day, the firstborn said to the younger, “Behold, I lay last night with my father. Let us make him drink wine tonight also. Then you go in and lie with him, that we may preserve offspring from our father.” 35 So they made their father drink wine that night also. And the younger arose and lay with him, and he did not know when she lay down or when she arose. (Gen 19:32-35). 

This passage is striking in light of "affirmative consent" policies on some college campuses. Here two women roofie a man. That's a case of women raping a man (specifically a case of incest). They get him drunk to incapacitate him in order to sexually assault him. 

Somehow I doubt this will become the locus classicus of feminist theology.
