That’s the part that I think perhaps wasn’t communicated well enough. So much focus is put on the women getting it that their little pea brains decided that women were the only ones affected.
…Or maybe not. They disapprove of sex outside of marriage for men too… officially.
In reality they have a much more complicated relationship with it; a man who doesn’t sleep around isn’t virile enough, but in their eyes marriage is sacred, so boys are told ‘don’t have sex before marriage’, with a pretty hefty nudge-nudge-wink-wink and boys-will-be-boys attached.
But if they get sick for it, oh well, they were warned!
