Looking at these particular images and poses, one cannot help asking oneself exactly that.
It would be a better idea if the fathers vowed to teach their daughters all about contraception. Yes, this is creepy and abusive. Even if it’s the daughter’s wish in the first place, their parents should have enough common sense to refuse. No sex before marriage - good grief. Marry a sexual creep and not find out until it’s too late? Who on earth wants that? Doesn’t anybody think of the consequences of this stupid prenuptial vow? If the girls can’t, at least their parents should.
