Alcohol, smoking and sexual health: what they really do to desire and erections

Illustration: Men’s Health
Quick answer

A small amount of alcohol may lower inhibitions, but more makes erections and orgasm harder, reduces sensation and affects judgement. Long-term heavy drinking lowers desire and testosterone. Smoking and tobacco damage blood vessels, a major cause of erectile difficulties, and can affect fertility. Cutting down or quitting often improves sexual health within months.

Key takeaways
  • Alcohol may relax you, but more makes erections and orgasm harder.
  • Smoking narrows blood vessels needed for erections.
  • Both can lower desire and affect fertility.
  • Cutting down often brings noticeable improvement.

Many people use a drink to relax before intimacy. A little may help with nerves, but more often works against you.

Alcohol and sex

  • Short term: too much reduces sensation, makes erections and orgasm harder and affects consent and judgement.
  • Long term: heavy drinking can lower desire, affect hormones and cause relationship conflict.

Smoking and tobacco

  • Damage blood vessels, reducing blood flow needed for erections.
  • Linked to lower fertility.
  • Affect stamina and overall health.

This applies to cigarettes, bidis and chewing tobacco.

Why ‘liquid courage’ backfires

Using alcohol to manage nerves can create a cycle: drink to relax, struggle to perform, feel more anxious. See sexual performance anxiety.

What helps

  1. Set limits on drinking, especially before intimacy.
  2. Get support to quit smoking or tobacco.
  3. Exercise and sleep well.
  4. Manage stress without substances. See how to manage stress and anxiety.
  5. Talk to your partner.

Myths and facts

  • Myth: Alcohol improves performance. Fact: More than a little makes it harder.
  • Myth: Smoking only affects lungs. Fact: It affects blood flow everywhere.
  • Myth: The damage is permanent. Fact: Many improvements follow cutting down.
