Abstract: According to a survey of approx. 700 people on the influence of alcohol and 13 other drugs on their sexual perception, sexual behaviour and condom use, it was found that most drugs increase sociableness, the desire for sex, orgasm strength and sensitivity to touch. However, they also lower the ability to orgasm and maintain an erection, and increase the risk of unsafe sex. The greatest risks here, in up to 75% of cases, occur after the consumption of GHB/GBL or crystal, and in 20 to 50% of cases following the consumption of speed, ecstasy, poppers, cocaine or large quantities of alcohol.
