This patch will prevent peaceful unicorns from running away from you
if you're a female virgin.  Priestesses don't get treated differently
from anyone else -- a Google search suggests that priestesses just
have more reasons to deal with unicorns but don't have it any easier.

You need to apply my conducts patch as well, or any other patch that
sets u.uconduct.sex when the player dallies with a foocubus.
