I remember from Cerulean Sins that Asher consulted a surgeon, that is why he can have "teh sex" with Anita now. Because if I remember correctly, Jean-Claude was worried that the holy water had caused so much damage that Asher would no longer be able to "perform" properly but when Anita, Asher, and Jean-Claude were together and Anita undressed him, Jean-Claude made a comment about it and Asher said that the surgeon said it was only the foreskin, or something, and it was easily fixed. Then there were joyous tears (seriously, I think there were).

I have no idea how I remember any of this...
