Earlier this year, I wrote two articles about BDSM—bondage, dominance/submission, and sadomasochism. I argued that BDSM, unlike homosexuality, was inherently problematic and wasn’t an orientation. Defenders of BDSM—Dan Savage, Jessica Wakeman, Clarisse Thorn, Jillian Keenan, and dozens of Slate commenters—wrote back, rejecting these arguments. Then, two months ago, Dutch psychologists published a study of kinksters and mental health. I started digging around. There isn’t much quantitative research on this population, but I found a few decent studies that can help us clarify the debate. Is BDSM sick? Let’s look at the evidence.
1. How many people do BDSM? There’s only one good random-sample survey on this question. It was taken in Australia a decade ago. Nearly 20,000 people between the ages of 16 and 59 were interviewed by phone. In the whole sample, 1.8 percent of men and 1.2 percent of women answered yes to the question, “In the last 12 months, have you been involved in B&D or S&M?” (The question went on to explain, “That’s bondage and discipline, sadomasochism, or dominance and submission.”) Among respondents who were sexually active, the BDSM minority barely increased, to 2 percent of men and 1.4 percent of women. Among those who had a sexual partner in the previous year, the figure was 2.2 percent of men and 1.3 percent of women.
That’s roughly equivalent to the sexually active gay population, as measured by similar self-reporting. In the Australian survey, the authors reported “less than 2 per cent of men and women” said they’d “had sex with a same-sex partner in the past year.” The percentage of respondents who said they’d ever had a gay sexual experience (not just in the last year) was higher—6 percent of men, 9 percent of women—and presumably the same is true of BDSM. In the Dutch study, for instance, 448 respondents accessed and completed a BDSM survey through a website devoted to personal secrets. Of these, 3 percent “indicated having had previous BDSM experience.”
2. Is it an orientation? Previously, I argued that homosexuality is fixed (an orientation) but that BDSM is flexible (a lifestyle). Kinksters replied that BDSM, too, is an orientation. What do the data show? Mostly flexibility. In a study of Finnish BDSM enthusiasts, 27 percent “endorsed a statement suggesting that only sadomasochistic sex could satisfy them,” but only 5 percent “no longer practiced ordinary sex.” Furthermore, 40 percent had changed their “preference” or “behavior” (in the authors’ words) from sadism to masochism or vice versa. In another study, conducted in southern California, “32% of the sample indicated that BDSM play occurred less than half the time they spent in sexual activity with partners, and just 11.2% indicated that BDSM play was their only form of sexual activity.” The core group, dedicated to BDSM, seems vastly outnumbered by dabblers.
3. Is it physically dangerous? That depends on what you’re doing. In the Finnish study, bondage and flagellation were standard: More than 80 percent of the sample had done them in the preceding 12 months. The riskier stuff was far less common: piercing (done by 21 percent of the sample), skin branding (17 percent), hypoxyphilia (suffocation games, also known as breath play—17 percent), electric shocks (15 percent), and knives or razor blades (13 percent). The California study found a similar pattern: Bondage, flogging, and spanking were standard (more than 80 percent had done them), but other practices—“fire play” (20 percent), “piercing play” (20), cutting (14), branding (9), and scarification (5)—were rarer. Some potentially dangerous activities were surprisingly common—“electric play” (42 percent), “knife scenes” (40), and “breath play” (27)—though in many cases, the implements were probably just props. It looks as though about 20 percent of these folks are actually cutting, burning, zapping, or partially suffocating each other.
That’s a minority, but it’s still worrisome. In the Finnish sample, those who said they’d previously suffered sexual abuse—23 percent of the women, and 8 percent of the men—were particularly problematic. According to the authors, “Visits to a physician because of injuries obtained during sm-sex were significantly more common among the abused respondents (11.1%) than among the non-abused respondents (1.8%).”
BDSM community leaders preach the importance of “safe words”—prearranged signals that the restrained, flogged, or dominated participant can use to withdraw consent and stop the action. In the Finnish study, 90 percent of the sample said they “sometimes” incorporated such words in their encounters. But less than half did so “without exception.” That, too, is a problem. ...
