I don’t suppose that anyone has even considered not letting their current significant other video or photograph them in a compromising state or position? If you don’t want nude pictures posted, don’t pose nude!
Do you think this sort of thing never happened before the internet? In my late teens, I recall some girl letting her boyfriend take nude Polaroids of her, which duly got passed around among his mates. Why? Because a naked photo was proof he was having sex! He was a jerk, of course he was — he also suffered an uncomfortable ten minutes at the hands of her brother and the snaps were destroyed. But at the same time, she wasn’t being all that smart, either, was she?
