Swinging (sexual practice)
Sexually-transmitted infections

A Dutch study that compared the medical records of self-reported swingers to that of the general population found that STI prevalence was highest in young people, homosexual men, and swingers. However, this study has been criticized as not being representative of swinger populations as a whole: its data was formulated solely on patients receiving treatment at an STI clinic. In addition, according to the conclusions of the report, the STI rates of swingers were in fact nearly identical to those of non-swinging straight couples, and concluded that the safest demographic for STI infection were female prostitutes. According to the Dutch study, "the combined rates of chlamydia and gonorrhea were just over 10% among straight people, 14% among gay men, just under 5% in female prostitutes, and 10.4% among swingers."
