Recreational drugs - both legal and illegal - have been combined with sex for an extremely long time, partially due to how they can make orgasms and other pleasurable feelings more intense. However, drugs can also reduce the intensity of orgasms, and can have a multitude of effects on many other aspects of sex, including increasing or decreasing sex drive, changing how the body responds to sex (such as causing erectile dysfunction or premature ejaculation), and increasing sexual risk taking. This unpredictability is because sex - and sexuality - are complicated, relying on intricate relationships and changes in biology and emotions, all of which can be affected by drug use. It's even possible to become sexually dependent on drugs, which can alter behaviour, feelings, and make it hard to enjoy sex - or function properly - without them. It goes without saying that drugs can be dangerous, and using them for any reason can develop into a substance abuse issue. Anyone who is struggling with substance abuse should seek help, either from a doctor, mental health professionals, or support groups
