From the mid-1980s there was active lobbying against gay bathhouses, blaming them for the spread of STIs, in particular HIV, and this forced closures in some jurisdictions, particularly in the United States.
[9][10] Sociologist Stephen O. Murray writes that, "there was never any evidence presented that going to bathhouses was a risk-factor for contracting AIDS.
[15][16][17][18] In a 2015 US survey, a significantly larger percentage of men than women responded that they had any lifetime experience of a threesome (17.8 vs 10.3) or group sex (11.5 vs 6.3).
The section was enacted by the Immorality Amendment Act, 1969 and remained in force until it was found to be unconstitutional in 1998 by the Constitutional Court in the case of National Coalition for Gay and Lesbian Equality v Minister of Justice.
[24][25] In Canada, in a 2002 decision regarding a case in which three people were engaged in sexual intercourse, the Court of Queen's Bench of Alberta declared section 159 of the Criminal Code in its entirety to be null, including the provisions criminalizing anal sex when more than two persons are taking part or present.
[26] In June 2019, C-75 passed both houses of the Parliament of Canada and received royal assent, repealing section 159 effective immediately.
In the early 1950s, for example, it was alleged that teenage girls, mainly throughout the Southern and Midwestern United States were forming "non-virgin clubs", in which they organized and held sex orgies with reports of couples being paired off by drawing numbers from a hat.
In New York, rumors began that teens had been taking days off from school to attend "hooky parties" while their parents were at work.
At these events, females wearing various shades of lipstick reportedly took turns fellating males in sequence, leaving multiple colours on their penises,[35] ignoring the fact that in such a situation the colors would blend.
However, sex researchers and adolescent health care professionals have found no evidence for the existence of rainbow parties, and as such attribute the spread of the stories to a moral panic.
