I fully understand 'bukkake'. Fully understand 'gokkun'. The two shouldn't be mixed as 'gokkun' is the (or should be) the classier of the two. A woman being 'humiliated' by men (willingly or otherwise) vs. a woman who enjoys being 'fed' by men who love women - the misogynistic component makes the difference.
