What Makes Men Addicted to Pornography and Women to Romance Novels (and Chocolate)?

When we experience love at first sight, a chemical, phenylethylamine(PEA), floods the brain. PEA, an amphetamine-like chemical, makes us feel euphoric and aroused. Surprisingly, we don’t even need an actual person present to have a surge of PEA. This chemical increases even when we read a romance novel or see a sexy picture.1 Yes, it is the romance novel that turns on this amphetamine-like PEA substance for women and sexually explicit pornography that turns it on for men.2

PEA causes us to feel so good but it also can cause us to become addicted to whatever stimulates it.  Then, just as an addiction to amphetamines can induce cravings and withdrawal, we become dependent on seeking out whatever will increase our PEA.

Driven by this chemical hunger, we might even experiment with eating chocolate because chocolate contains PEA. Maybe this is why a box of chocolates is a romantic gift, in the hope that the surge of PEA will increase passionate feelings. Indeed, one study showed that participants indicated greater interest in initiating a relationship with a potential partner when exposed to a sweet taste.3 There is a downside, however.  Chocolate does contain PEA but the PEA is metabolized so quickly that it doesn’t have time to have much effect on the brain.4
