It's very healthy for a young girl to be deterred from promiscuity by fear of contracting a painful, incurable disease, or cervical cancer, or sterility, or the likelihood of giving birth to a dead, blind, or brain damaged baby (even ten years later when she may be happily married).
Like the pagans of old, unaffected by climate, the British were now dancing around a giant phallus. Unlike the pagans theirs was a sterile phallus, disarmed by condoms and pills - the first heathen sexual cult to be based around sterility rather than fertility. - Peter Hitchens
