Humans are hopefully capable of more than just that. Especially because pornography is so ridiculously easy to obtain that if we don't control out impulses then we are fucked as a species.
Same goes for other things such as food, entertainment, attention, etc.
Excesses of these things were already issues for people 1000 years ago, and they are cheaper and more accessible than ever now.
