16 Little-Known Facts About Love

1. Love and obsessive-compulsive disorder share similar physiological manifestations.

There's a scientific basis for your inability to stop thinking about someone: MRI scans show that being in love sends blood flow to the brain's "pleasure center"—the same area that governs obsessive-compulsive disorder (OCD). Furthermore, feelings of love and fantasies about another person also lower serotonin levels, a phenomenon commonly seen in OCD sufferers. The inability to stop thinking about someone while in love shares similar physiological characteristics with OCD, which explains why, when we first fall in love, our attention is usually focused solely on our partner.

2. Watching romantic movies together can reduce the divorce rate.

Couples who enjoy watching romantic movies together are more likely to use the content of those movies as topics of conversation in their daily lives. This fosters a habit of focusing on the quality of their marriage, leading to frequent discussions and timely adjustments. Consequently, they experience more intimacy, making their marital relationship stronger. Research suggests that couples who enjoy watching romantic movies together also have a lower divorce rate.

3. A humble personality makes it easier to find a partner.

Low-key people have a better chance of finding a partner! Experiments show that humble people are the most popular and are more easily forgiven for occasional offenses, suggesting that humility can play a significant role in repairing relationships. In the future, "humble character" may even surpass "good looks" to become the sexiest personality trait of the 21st century.

4. Couples with happy sex lives usually have similar DNA.

We know that people instinctively tend to choose spouses who are similar in age, race, religion, income, and family upbringing. In fact, we also unconsciously choose marriage partners who share similar DNA. Researchers believe that genetic similarity is far more significant than other factors such as educational background in happy couples.

5. Women can become more sexy by controlling their voice.

Studies have found that women can consciously control their voices to make them sound more pleasant and sexually attractive. And their voices become incredibly sexy during sex. Almost all men prefer a high-pitched, more feminine voice, but when a woman deliberately lowers her voice to sound sexier, it's often a subtle hint to her crush.

6. Traveling together can enhance intimacy.

Long road trips greatly enhance intimate communication between couples because the confined space allows for a rare moment of focused attention. This provides an opportunity to better understand each other. Furthermore, the change of environment and the removal of distractions during a journey can create a surprising and refreshing change in the otherwise monotonous act of intimacy. Therefore, traveling together is one of the best and most natural ways to improve a couple's relationship.

7. Intuition can predict marriage trends.

People often wonder before marriage: Is he/she truly the one I love? A study published in the journal *Science* suggests that the answer is often already known subconsciously. This indicates that people's intuitive judgments about marriage are often more accurate.

8. Most people have been infected with HPV.

Here's a statistic that might alarm you: over two-thirds of healthy American adults have been infected with one or more types of human papillomavirus (HPV), a virus that can be transmitted through sexual intercourse or oral sex. However, the less frightening news is that only one in 26 of these individuals is infected with a type of HPV that can lead to cervical cancer, throat cancer, or genital warts. This is because, under normal circumstances, the body's strong immune system can clear the virus automatically, even without treatment. But if you want to enjoy 100% sexual satisfaction, in addition to choosing your sexual partner carefully and maintaining good hygiene, exercising and strengthening your immune system are also crucial.

9. Birth control pills can affect a woman's "views on men".

American sexologists have found that taking birth control pills can affect a woman's sexual preferences! Specifically, women taking hormonal birth control pills experience a decrease in interest in men, are less easily seduced, and have relatively lower satisfaction with their relationships. The widespread use of birth control pills also challenges men's earning power, because for these women, a high-paying job is the most important "sex appeal" for men.

10. Women during ovulation are more attracted to muscular men.

Numerous studies have shown that women experience a higher libido during ovulation, are more attracted to muscular men, and are less concerned with a man's intellectual development. They are also more likely to choose men with a slight tendency towards violence as short-term sexual partners, but are less inclined to establish long-term sexual relationships. Experts analyze that this is a natural selection process in the biological world; the egg, during its maturation period, naturally and subconsciously seeks out a sufficiently strong sperm.

11. Sex burns calories, marriage makes bones stronger.

An hour of sex burns just as many calories as 30 minutes of jogging! Studies show 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 101 calories and women burn 69 calories. Furthermore, research indicates that men and women with regular sexual partners have higher bone density, suggesting that marriage contributes to bone health. This further demonstrates that regular sex is beneficial for both physical and mental well-being.

12. Low blood sugar can easily lead to disputes between partners.

Studies have found that some marital discord and arguments may be caused by low blood sugar. Couples with lower blood sugar levels are more likely to be "annoyed," and the chances of them arguing or even getting into physical fights are also higher. To increase satisfaction in your intimate life, it's best to ensure you have a delicious dinner before sex, as hunger can make people more sensitive and irritable.

13. Afterplay is more effective than forplay in increasing sexual satisfaction.

For satisfaction in a relationship, the kisses, caresses, and loving conversations after sex are just as important as the sexual act itself. Relationship experts explain that this may be related to the release of oxytocin. Oxytocin is continuously released during sex and during skin-to-skin contact after orgasm, so couples who prolong their sexual experience are able to build a stronger emotional bond.

14. Lowering cholesterol levels in men's blood vessels can improve sexual satisfaction.

Did you know that besides cardiovascular disease, high cholesterol can also cause erectile dysfunction in men? In fact, erectile dysfunction can also be considered a warning sign of cardiovascular disease. Fortunately, research in the United States shows that men taking cholesterol-lowering medications can also experience improvements in their sex life. So, for your sexual well-being, help your man lose weight and lose fat!

15. Both men and women occasionally fake orgasms during sex.

People often assume that faking orgasms stems from not enjoying the sexual experience and simply wanting it to end quickly. However, sex experts believe that sex itself has a performative aspect, and sometimes it's quite entertaining when both partners lose control. It's not just women who fake orgasms; men do it too, and often do so. The reason is the same as women's: they don't want to disappoint their partner. In reality, faking an orgasm occasionally is no big deal; enjoying the experience is what matters most.

16. A flushed face during sex will make you more satisfied.

Developing red spots all over your body during sex? Don't worry. This could be "sex rash," a natural reaction of your body to increased blood flow and skin temperature. It will subside naturally as you calm down. It most likely appears on the cheeks, chest, bikini area, or covers the entire body. Scientists believe that women who develop sex rash are more likely to achieve satisfying orgasms. So, if you experience localized skin flushing during sex, don't worry about it; just enjoy the experience.
