I agree. It seems to me that they make much more of gay couples kissing than straight couples. You rarely see any of the couples smooching yet Robert/Aaron and Charity/Vanessa are always at it, seems as if the writers are making a point of how PC they are, but why?
I am still wondering as to how the very young actors interpret some scenes e.g Rodney and friend half naked etc. IMO they are too young to be exposed to this behaviour.
