Frequent alcohol consumption and smoking can affect libido?


Hello Dr.
Liu: I haven't had sexual intercourse for almost 5 years, but during this time, I have been engaging in self-stimulation 3 to 6 times a month.
I have a habit of excessive drinking and smoking, and my job is responsibility-based, which requires me to sit in front of a computer all day.
I also do not exercise regularly.
Recently, when I wanted to have sex with my girlfriend, I found that while I could achieve an erection, the glans did not become firm, which left me confused.
My previous sexual experiences were normal, so why do I have this issue after 5 years without intercourse? Could it be related to my drinking habits?

That's right! Drinking alcohol and smoking are "sexual" killers, and there are many habitual regressions that can occur with a lack of "sex." Please take care!

The relationship between alcohol, smoking, and sexual function is complex and multifaceted. Both alcohol and nicotine can have significant effects on libido and erectile function, and your situation reflects some of the common issues associated with these substances.

Firstly, alcohol is a central nervous system depressant. While moderate drinking may initially lower inhibitions and increase sexual desire, excessive alcohol consumption can lead to a decrease in sexual arousal and performance. Chronic alcohol use can impair the body's ability to achieve and maintain an erection. This is due to several factors, including the impact of alcohol on hormone levels, blood flow, and nerve function. In your case, if you are consuming alcohol regularly, it could very well be contributing to the difficulties you are experiencing with erectile function.

Nicotine, found in cigarettes and other tobacco products, also has detrimental effects on sexual health. Smoking can lead to vascular problems, which are crucial for achieving an erection. Nicotine constricts blood vessels, reducing blood flow to the penis, which is essential for an erection. Additionally, smoking can lead to hormonal imbalances and reduced testosterone levels, further impacting libido and erectile function. Even if you smoke only a few cigarettes a day, the cumulative effects over time can still be significant.

Your mention of having not engaged in sexual intercourse for five years may also play a role in your current difficulties. The body can undergo changes during periods of sexual inactivity, and psychological factors can also contribute. Anxiety about performance, fear of intimacy, or even changes in self-image can all affect sexual function. It is not uncommon for individuals who have been inactive for a long time to experience anxiety or stress when they attempt to engage in sexual activity again, which can further complicate the situation.

Moreover, your sedentary lifestyle, characterized by long hours at a computer without exercise, can also contribute to erectile dysfunction. Regular physical activity is essential for maintaining good cardiovascular health, which is crucial for sexual function. Exercise improves blood circulation, boosts testosterone levels, and enhances overall mood, all of which can positively impact libido and erectile function.

In summary, both alcohol and smoking can significantly affect libido and erectile function. The combination of these habits, along with a sedentary lifestyle and the psychological factors associated with long-term sexual inactivity, likely contributes to the difficulties you are experiencing. It would be beneficial to consider reducing or eliminating alcohol and smoking from your lifestyle, as well as incorporating regular physical activity. Additionally, discussing your concerns with a healthcare professional can provide you with tailored advice and support, including potential treatments for erectile dysfunction and strategies to improve your overall sexual health.
