Republicans and Democrats are also divided on sexual fantasies

While both parties reported they fantasize at the same rate — several times a week — the themes of those fantasies were divided along party lines. Republicans tended to prefer fantasizing about sex outside of marriage: “things like infidelity, orgies and partner swapping, from 70s-style ‘key parties’ to modern-day forms of swinging,” Lehmiller wrote. Republicans also reported more voyeuristic fantasies like going to a strip club or watching one’s partner have sex with another person.

Democrats, on the other hand, were more likely to favor fantasies that included domination and power dynamics, including BDSM. According to Lehmiller, “The largest Democrat-Republican divide on the BDSM spectrum was in masochism, which involves deriving pleasure from the experience of pain.”
