Men with higher-pitched voices have a higher sperm count.

In a study involving multiple European countries, it was found that although women perceive men with deep voices as more masculine and attractive, their sperm concentration is lower compared to men with higher-pitched voices. Women's vocal pitch tends to increase during ovulation, which is a natural instinct to attract male attention.

Regular sexual activity improves memory.

A recent study conducted at a university in Canada found that individuals who engage in frequent sexual activity have better memory compared to those who have infrequent sexual encounters. The study focused on heterosexual couples under the age of 30 and observed changes in the hippocampus, a vital area of the brain responsible for emotions, memory, and the nervous system. The results showed that frequent sexual activity enhances the ability to recall abstract words, leading to improved memory.

Genetics play a role in a person's first sexual experience.

While the first sexual experience is often a personal choice, recent research suggests that genetic factors directly influence the timing of an individual's first sexual encounter. Studies conducted on twins, who were separated at birth, have shown a strong genetic correlation in terms of impulsiveness, conservatism, and adventurousness, all of which can influence a person's decision regarding their first sexual experience.

Men produce more reproductive cells than women.

There is a significant difference in the number of reproductive cells produced by men and women. At birth, females have around 1-2 million eggs, but by the time they reach puberty, only about 300,000-400,000 eggs remain, with only 300-400 eggs being released before menopause. On the other hand, a healthy male produces over 500 billion sperm cells throughout his lifetime, with each ejaculation releasing around 1.2 million sperm cells.

The clitoris is an internal organ.

While most people are aware of the external part of the clitoris, stimulating this small protrusion can bring intense pleasure to women. However, the majority of the clitoris is actually located internally within the pelvic region. During sexual arousal, the clitoris engorges and wraps around the surrounding vaginal area, providing heightened sexual pleasure. The external tip of the clitoris, which is visible, plays a crucial role in sexual stimulation due to its high concentration of nerve endings, which is twice as many as the nerve endings in the male penis.

Sexual activity can slow down the aging process.

A study conducted at the Royal Edinburgh Hospital in the UK concluded that couples who engage in sexual activity at least four times a week appear to be over a decade younger than their actual age. The release of adrenaline, dopamine, and norepinephrine during sexual activity contributes to maintaining the firmness of skin cells and muscle relaxation, which can slow down the aging process.

Soaking your feet in warm water can enhance sexual pleasure.

Traditional Chinese medicine suggests that there are several acupoints on the feet that can enhance sexual pleasure. Research conducted at the University of Groningen in the Netherlands also supports this claim, showing that warm feet can increase female orgasm intensity by 30% and accelerate sexual response. Soaking your feet in warm water before engaging in sexual activity promotes blood circulation in the feet, effectively stimulating sexual desire and enhancing the overall sexual experience.

Semen is surprisingly nutritious.

On average, a single ejaculation contains about 15 calories, which is equivalent to the protein content of a large egg. Additionally, semen also contains vitamins C and B12, calcium, magnesium, potassium, and zinc, making it a surprisingly nutrient-rich substance.

Wait for at least an hour after a meal before engaging in sexual activity.

After a meal, there is an increase in gastrointestinal activity as blood rushes to aid in digestion. As a result, the blood flow to the reproductive organs is relatively reduced. It is generally recommended to wait for about an hour after a meal to allow sufficient blood flow to the sexual organs, which can enhance the quality of sexual activity.

Regular sexual activity boosts the immune system.

Engaging in sexual activity at least once or twice a week can increase the production of immunoglobulin A (IgA), an antibody that plays a crucial role in immune defense. IgA is found in saliva and mucous membranes and helps protect against infections, including colds and flu.

Emergency contraception should not be used more than three times a year.

The dosage of emergency contraception is equivalent to eight days' worth of regular short-acting oral contraceptives. Excessive use can lead to menstrual irregularities, ovarian suppression, and hormonal imbalances. It is advised to use emergency contraception no more than three times a year and limit its use to once a month.

Sex enhances a woman's attractiveness.

During sexual activity, a woman's estrogen levels double. Estrogen is often referred to as the fountain of youth for women, as it promotes healthier hair, smoother skin, and a more youthful appearance. Additionally, sexual climax increases blood flow throughout the body, resulting in a radiant complexion, flushed cheeks, and redder lips. Therefore, sex can have a rapid beautifying effect for women.

Diet can affect the smell of semen.

Research has shown that food directly influences the smell of semen. Consumption of sugary fruits like kiwi, watermelon, and pineapple can make semen taste milder, while beer and coffee can make it smell stronger and more bitter. Consuming fatty foods can make semen thicker, while acidic fruits like cranberries and plums, as well as alcohol, can make semen taste sweeter. Dairy products, due to bacterial action, can give semen an unpleasant odor.

Women are more attracted to muscular men during ovulation.

Women experience increased sexual desire during ovulation and are more attracted to muscular men, regardless of their intellectual capabilities. They are also more likely to choose men with a slightly aggressive nature as short-term sexual partners but may not prefer them for long-term relationships. Experts believe this is a natural selection process, as during ovulation, the female body subconsciously seeks a genetically strong sperm.

Quality sleep is crucial for a satisfying sexual experience.

Adequate sleep is essential for a fulfilling sexual experience. Lack of sleep, less than six hours per night, can lead to sexual fatigue. Fragmented sleep can also decrease anticipation for sex, as sleeping in three separate intervals of ten hours is less effective than sleeping for seven continuous hours.

Afterplay is as important as foreplay for sexual satisfaction.

Engaging in post-sexual activities such as kissing, caressing, and loving conversations is equally important as foreplay. Relationship experts explain that this may be due to the release of oxytocin, also known as the "cuddle hormone," which continues to be released during skin-to-skin contact after sex and orgasm. Couples who prolong the afterplay phase can establish a stronger emotional connection.

A fulfilling sex life can enhance a woman's sense of smell.

Engaging in quality and meaningful sexual experiences can stimulate the growth of more neurons in the olfactory center of the brain, enhancing a woman's sense of smell. However, olfactory neurons are only activated when the cerebral cortex is stimulated, meaning that routine and unexciting sexual encounters do not contribute to improving the sense of smell.

Sex burns calories and strengthens bones.

One hour of sexual activity burns as many calories as 30 minutes of jogging. Studies have shown that men burn an average of 4.2 calories per minute during sex, while women burn 3.1 calories per minute. In a single sexual encounter, men burn approximately 101 calories, and women burn around 69 calories.

Too frequent sexual activity can decrease sperm count.

Excessive sexual activity can lead to a decrease in sperm quantity and density. It may even result in the release of immature sperm that cannot fertilize an egg, reducing the chances of pregnancy. For women who can develop specific immune responses, excessive exposure to their partner's semen can trigger the production of anti-sperm antibodies, hindering sperm movement and affecting the ability to conceive.

Avoid cold drinks and showers immediately after sex.

After sexual activity, it is advisable to consume warm beverages and avoid cold drinks or showers. During sexual activity, blood vessels, including those in the gastrointestinal tract, are dilated. Introducing cold beverages or showers immediately after sex can cause discomfort or even abdominal pain due to the sudden exposure of the gastrointestinal mucosa to cold temperatures. Similarly, the dilation of skin blood vessels makes the heart work harder when exposed to cold.

Sexually active individuals are at a higher risk of contracting sexually transmitted diseases.

Approximately 80% of sexually active adults will contract a sexually transmitted disease at some point in their lives. Therefore, it is crucial for sexually active individuals to practice safe sex and take necessary precautions to protect themselves from sexually transmitted infections.

Birth control pills can affect a woman's preference for long-term relationships.

Birth control pills can alter the brain's chemistry in women, influencing their interest in long-term committed relationships compared to seeking sexually compatible partners. The hormonal changes caused by birth control pills can affect a woman's attraction to different types of partners, potentially shifting her preferences.

Hard nipples do not always indicate sexual arousal.

While it is commonly believed that hard nipples indicate sexual arousal in women, this is not always the case. Factors such as cold temperatures or friction from clothing can also cause nipples to become erect.

Being drunk does not improve sexual performance.

Moderate alcohol consumption can enhance sexual desire, but being intoxicated can negatively impact sexual performance. Some individuals believe that combining alcohol and sexual stimulation can create a perfect blend, disregarding the fact that being in an impaired state can significantly reduce the quality of sexual activity. Long-term excessive alcohol consumption can even lead to a decrease in sexual sensitivity and sexual dysfunction.

The start-stop technique can help improve sexual stamina.

Delaying ejaculation through the start-stop technique can improve sexual stamina, prolong sexual activity, and enhance sexual satisfaction. The technique involves pausing just before reaching ejaculation and using pelvic floor muscle contractions to control the urge to ejaculate, thereby improving control and intensifying the pleasure of ejaculation. This technique can be beneficial for individuals who want to prolong sexual encounters.

Even with a regular sexual partner, 78% of men and 53% of women satisfy their sexual needs through masturbation. However, this topic is not often openly discussed.
