Narcotic substances often reduce sexual desire and interest, leading to problems with erection and orgasm. Taking them can worsen health and cause risky behavior. They increase the likelihood of dangerous situations. Research shows a link between their use and sexual abuse. Other risks include decreased inhibitions, increasing the risk of unprotected sex and sexually transmitted infections. Dependence on them can reduce the pleasure of sex and disrupt relationships, and sharing needles increases the risk of HIV. It can be said that they pose a serious threat to sexual health as well. Sex requires coordination of hormones, neurotransmitters, physiological changes, emotions and thoughts. Like drugs, they can change various processes in the body. For example, antipsychotic drugs alter hormone levels, especially in men, leading to sexual problems. (2)(3) How they affect sexual health: 1. Libido. Drugs alter libido by increasing or decreasing sexual desire. The effect may be different, depending on the type, dose and frequency of administration. They can prompt a desire for more sex, or vice versa. They can also lead to unpredictable effects on libido regardless of the circumstances. 2. They can affect physical arousal independent of psychological desire for sex. They can cause sexual dysfunction. Studies show that even trying them recreationally can be addictive and lead to erectile problems. 3. They are often taken to increase sexual pleasure and facilitate orgasm during sex, but are more likely to have the opposite effect of making it more difficult to achieve orgasm. For example, alcohol and opioids can delay ejaculation. 4. Greater sexual risks are taken under the influence of alcohol or drugs. Some may view this behavior as positive, as substances reduce anxiety and inhibitions. But this can lead to the resorting to potentially harmful sexual practices, including sexual violence or engaging in unsafe sexual activities, which can have negative consequences for health and well-being. Mind-altering substances affect decision-making. A 2021 study notes that their use alters sexual norms and makes it harder to have sex.
