The films are being banned (Refused Classification) on one of two grounds:
1) That the depictions are a form of urination which is banned under the label of ‘golden showers’ in the Classification Guidelines or
2) Female ejaculation is an ‘abhorrent’ depiction.
The Board has also started to ban depictions of small-breasted women in adult publications and films.
I was actually quite surprised to hear urination is already prohibited in porn. Apparently UK censors tried to ban female ejaculations a while back, but were convinced by a gang of feminists that it is not an urban myth.
And the small breast thing... I find it quite ironic that porn censorship is picking up on the exact topics that are most likely to enrage feminists. Like we aren't already all obsessed by perfect silicone breasts. Now large breasts are the only ones allowed naked?!
