I saw that holy magic damage is based on virility, but the only holy attack I got is head pat so that isn't really relevant. The most use I have found for virility is that it increasing the value of your seed to the Foxy witch baker in the woods.
there's another holy weapon called demon layer that you can get from vivian if you have enough relationship points with her and answered her quiz.
Lillian (the priestess), not Vivian (the innkeeper).
fun fact: if you use the holy head pet on feng for the first time you fight her she will let you thought without a fight.
also another fun fact: never use holy head pet on sofia, she will destroy you regardless of how many health you have
