I don’t blame people for not knowing this since Haguhagu’s Twitter got nuked a few months ago, which isn’t surprising since he gets banned at least once a year.
(And seeing what he tweets in his backup account... I see him getting banned soon again)
He tweeted, back when the manga was around volume 1,
that there’s no universe where Sasha is a virgin. Being sexually active is a key aspect of her character.
That said, this Sasha is pretty tame overall. Also, this doesn’t change her genuine feelings for Master or the evolution her character will have because of them.
