The three basic drives: Ingestion, Excretion and Reproduction.
Ingestion: a socially acceptable drive to dispaly in public - even has ritual xpectations attached to it that groups should undertake this drive together (eg Thanksgiving). Few taboos associated with this drive (eg cannibalism, religious constraints - pork).
Excretion: a socially unaccetable drive to dispaly in public (separate stalls for toilets). Associations with disease, dirt and waste. Also the requirement to adopt a vulnerable pose and reveal the genitals in order to excrete has psychological ramifications. Many taboos associated with this drive (eg Coprophilia, social anxiety, personal hygiene etc)
Reproduction: a socially unaccetable drive to dispaly in public, yet each one of us is public evidence of a private sexual act. Many variations on this drive, some with taboo issues (eg necrophilia, bestiality, incest, homosexuality)
>>1 Even subconciously posted about two of the drives mentioned: Why the fuck are people so obsessed with this shit now?
Fuck and shit. Reproducion and excretion.
Innate drive is innate.
Stop obsessing about other people's innate drives, get over your own, and move on.
