The answer is - Yes!

Certain substances like alcohol and drugs can indeed affect sexual function. Alcohol can lower inhibitions and impair judgment, potentially leading to risky sexual behaviors. It can also affect erectile function in men and decrease sensitivity in both men and women. Some drugs, such as antidepressants and antihypertensive medications, might have sexual side effects like reduced libido or difficulty achieving orgasm. Illicit drugs can also impact sexual performance and desire.

It's important to consider the potential effects of substances on sexual health and make informed choices. If you have concerns, it's best to consult a healthcare professional.
