I have a
headcanon that Grell is still a virgin. Grell adores being flirty to get the
attention of good-looking adult men, but when these men show their wish to get
more, then Grell becomes very shy and unconfident. Grell would like to have sex
with very tender and careful man, but still is unsure about that wish. Anyway,
I believe, Grell keeps their innocence only for William, because Grell is sure
that despite of his everyday rudeness Will will be tender with them at that minute.
