There is already a problem where girls develop quicker than boys during puberty. It wasn't unknown prior to mandatory ID checks on the doors of nightclubs for underage girls to get in to drink because they looked old enough. It works the other way too, many a time I see young women ask for a child ticket on the buses because the drivers don't ID them.

Are men and dating sites going to ask women for photo ID (which would have to apply to men too) with an increase in the age of consent to protect their backsides?
