Hidden Details for Enhancing Sexual Function: Caffeine Intake Strategies, Physiological Effects of Emotional Contact, and Lifestyle Monitoring

If you want passionate sex, have a cup of coffee before bed; if you want to ruin your sex life, the method is equally simple: drink one or two more cups. Coffee affects sex because it directly impacts the sympathetic and parasympathetic nervous systems. During the day, the sympathetic nervous system dominates, making people excited, while at night, the parasympathetic nervous system dominates, making people relaxed. If you drink more than two cups of coffee before sex, the sympathetic nervous system becomes over-excited, preventing you from achieving a relaxed and pleasant state of mind, thus reducing libido. However, for those who lack libido due to physical fatigue, a cup of coffee before sex can stimulate their mood and increase their sensitivity to external stimuli. Furthermore, avoid eating greasy food before sex, as a greasy and unhealthy meal can significantly suppress testosterone secretion, affecting erectile function.

Kissing can raise the heart rate of both men and women to 110 beats per minute, thus promoting blood circulation. The increased skin and muscle activity and accelerated blood flow during kissing can reduce wrinkles. The increased secretion of sex hormones during kissing releases neuropeptides that put the body's organs in a state of pleasure. Hugging is the best way to convey and release emotions. Physical contact between couples outside of sexual activity helps strengthen their love and makes both partners feel more energetic. A six-second hug can nourish both partners with love-increased heart rate, elevated blood pressure, and a warm current of happiness flowing through the body instantly.

A person's sexual function is closely related to their lifestyle. First, an irregular diet easily leads to obesity, high blood pressure, and penile vascular disease, while excessive consumption of raw or cold foods can affect libido and erection. Second, irregular daily routines and prolonged periods of busyness and stress can easily lead to sexual neurasthenia. Third, an imbalance between work and rest, especially overwork, easily depletes qi and blood, while prolonged inactivity leads to a decline in physical condition. Fourth, emotional distress, such as excessive grief or depression, can lead to impotence and premature ejaculation. Finally, irregular and unrestrained sexual activity easily leads to sexual fatigue, while too infrequent activity is also detrimental to sexual desire. Furthermore, accidental injuries to the genitals from activities such as cycling or playing football can directly damage penile blood vessels, resulting in impotence.

Many young couples now frequently use withdrawal as a method of contraception, but this method can be harmful to health. First, it has a high failure rate, as semen often enters the vagina before the penis is withdrawn. Second, it can easily induce premature ejaculation; men who strive for rapid ejaculation may quickly develop a habit of premature ejaculation. Third, withdrawal prevents men from fully enjoying orgasm, and over time, they may perceive the vagina as merely an organ for achieving ejaculation, damaging the overall psychological experience of sexual relations. Therefore, withdrawal is a poor choice for contraception. By paying attention to these subtle details, men can more scientifically maintain their reproductive health and emotional well-being.
