Do those with big dicks enjoy porn more because they can relate to the actors with big dicks? e.g. they can picture that cock being similar to theirs in size?
Also - is it more arousing to watch a bigger dick going inside a vagina than an average size one? does that add to the intensity of the orgasm?
