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 Stossel, "not one of them said don't do it," though some said "getting sexual thrills outside of marriage can threaten a marriage".
Nevertheless, swingers whom Stossel interviewed claimed "their marriages are stronger because they don't have affairs and they don't lie to each other." the information and communications technology revolution, together with improvements in medicine, has been effective in reducing some of the costs of swinging and hence in increasing the number of swingers.
John Stossel produced an investigative news report into the swinging lifestyle.
Stossel's report in 2005 cited Terry Gould's research, which concluded that "couples swing in order to not cheat on their partners".
Almost 70% of swingers claimed no problem with jealousy; approximately 25% admitted "I have difficulty controlling jealousy when swinging" as "somewhat true", while 6% said this was "yes, very much" true.
Swingers rate themselves happier ("very happy": 59% of swingers compared to 32% of non-swingers) and their lives more "exciting" (76% of swingers compared to 54% of non-swingers) than non-swingers, by significantly large margins.
Some people object to swinging on moral or philosophical grounds.
Most religious communities and moralists regard swinging as adultery, not withstanding that it is with the knowledge, consent or encouragement of one spouse to the other.

Approximately 50% of those who rated their relationship "very happy" before becoming swingers maintained their relationship had become happier.
