Snider (2001) states that pain can be involved with food and sex in regards to pleasure and pain. For example, eating hot peppers, spicy foods can be considered aphrodisiacs. The same dopamine-laden neurotransmitters in the brain are activated when risk behaviors related to both food and sex are desired. Anything the brain perceives as enjoyable will cause dopamine to flood our brain cells and build a memory ramp for pleasure. Food and sex are generally closely linked. They are physically in our brain, as well as emotionally. Good food is correlated with good sex.
“Some social theorists—Foucault, namely—argue that this tantalizing, ongoing search for culinary and carnal pleasure has much more in common than most pleasure-seeking eaters and sexual practitioners are even aware of themselves. These prime reasons consist of: purely pleasurable greed and bliss; masochistic endeavors; psychological confusion and/or substitution of the oral and phallic stages; desire for or purposeful loss of self-control; social status motives such as succumbing to trends or obtaining bragging rights; transcendence of gender and oft-established power roles with ‘foodie’ or sexual experimentation; among other reasons explored in the forthcoming sections” (135-136).
