People often think of “gender” as something simple — you’re either male or female. But in reality, gender is a multi-dimensional concept, shaped by biology, psychology, and society. To truly understand gender diversity, we need to distinguish three core dimensions: biological sex, gender identity, and gender expression (or social gender).

In traditional understanding, humans are classified as either male or female. However, with the advancement of biology and medicine, scientists have discovered that sex is not a simple binary system but a continuous spectrum.

Sex plays a crucial role in romantic relationships. Beyond satisfying physical needs, it’s also an important way to communicate emotions and maintain intimacy. But “how often is normal?” is a question that confuses many couples. Some believe that the more frequent the sex, the better the relationship — but in reality, every couple has different needs, habits, and rhythms. Over-comparing can actually create unnecessary pressure.

Many people grow up with little or incomplete knowledge about their own bodies. As a result, “sex” and “genitalia” are often surrounded by silence, taboo, and even shame. But understanding the male and female reproductive anatomy is not shameful—it’s a form of self-respect and essential sexual health education.

In conversations about intimacy, “sex” and “love” are often used interchangeably. But in reality, they represent two different—though often overlapping—human experiences. Understanding the difference between physical desire and emotional connection can help people build healthier and more meaningful relationships.

Mrs. Liu and her husband had been married for more than six months after meeting through a blind date.

In the past, my girlfriend once told me she liked to pee while standing in the shower.

Qianqian is in her early 30s, attractive, and preparing to get married to her long-term boyfriend. One day while taking a shower, she noticed that her pubic hair was quite thick, which made her feel a bit embarrassed.

A few days ago, while having sex with her boyfriend, she suddenly heard an embarrassing “popping” sound from her vagina.

Everyone has body hair. When we talk about body hair, we usually think of scalp hair, eyebrows, armpit hair, or leg hair — but often overlook a special type of hair: pubic hair.

Puberty is a natural and important stage of human growth. It marks the transition from childhood to adulthood and involves a series of physical and emotional changes triggered by hormonal activity. These changes occur in both boys and girls, though the timing and specific developments may vary. Understanding them helps reduce anxiety and build healthy self-awareness.

Many people grow up learning little about their own bodies. This lack of knowledge can lead to shame, fear, or misunderstanding about natural functions. In fact, male and female bodies are structured differently, but both are equally natural and worthy of respect. Learning basic anatomy is the first step to building healthy body awareness and sexual education.
