Article: Stemming from the work of psychologists and psychotherapists in late nineteenth and early twentieth centuries, the ego can be defined most basically as the self. After all, "ego" means "I" in Latin. The ego is the part of the mind responsible for acting as the “mediator” between the forces and drives of the superego (our conscience and our ideal selves) and our ids (the part that is responsible for satisfying our basic needs). The ego operates in reality, and is also responsible for mediating between our own needs and how to satisfy them within our environments. The ego maintains relations with others, reconciling the drives of the id and the superego with the outside world. Many psychologists posited their own theories of the ego based upon Sigmund Freud’s explanation of the ego. In other words, the male ego is not only a reflection of the individual self, but also of cultural definitions of masculinity and ideas about how men should think and act. Men's identities are thus shaped by social influences. Humans are social beings after all! In order to understand the male ego, it is necessary to understand how gender roles develop and function in society. Gender roles shape how people think and behave. Gender roles are sets of beliefs and actions that develop within specific cultural contexts and are associated with a particular biological sex (male or female). The roles help to differentiate between the sexes, so that men are seen to be one way and women another. By occupying these specific gender roles, some individuals function better within their particular social context while others may struggle. To understand the male ego, you need to understand how society shapes men's expectations of themselves. This is important because many men have developed ways of dealing with these social demands. In many cases, men aren't even aware of how society influences them. For example, most men don't really know how they came to be sports fans or think that blue, green, and gray are boys' colors while pink and purple are girls' colors. The male ego is driven by recognition, attention, and action. Men are assumed to be more active beings who do important things (such as political leaders, soldiers, scientists, etc.) and who are deserving of attention by others. In this vision of the male ego, men are driven by their physical strength, sex drive, and evolutionary biology as competitors for female attention to be competitive, to strive for greatness and power, and to avoid showing any emotion and weakness. For example, in most American communities, the male gender role is typically understood and described in active as opposed to passive terms. Men are courageous, strong, competitive, independent, and stable (in contrast, women are passive, emotional, weak, and more socially-oriented). To give another example, men in many communities in the western world are expected to avoid showing emotion. Remember the old saying "boys don't cry?" Instead, men are supposed to be macho and strong in the face of personal challenges, such as loss, grief, and sadness. A lot of men feel conflicted about having to be a certain type of man. For example, even though, statistically, the majority of men are heterosexual, what about men who don't identify as that? Or what about some men who enjoy pedicures and facials, things considered "girly" or feminine? It’s important to find out how individual men feel about and respond to these social expectations of how men should be because they will vary in each and every case.
Question: What is a summary of what this article is about?
Understand what the "male ego" is. Understand that gender roles are socially constructed. Learn the basic characteristics of the socially constructed male ego. Be aware that not all men feel comfortable performing these standard gender norms.
Article: Not topless or in your underwear, completely naked. Sleeping naked promotes relaxation and thus improves the quality of your sleep. On warm nights, sleep naked and skip bed-coverings, too, and see how good you feel fully exposed to the open air.  If you find sleeping naked difficult, work your way up to it. Shed one piece of clothing, for example your pajama top, and when you’re accustomed to sleeping without that, shed the next piece, and so on until you’re sleeping nude. Try opening a window near your bed (keeping the blinds closed) to let a breeze in. Remember that part of being a naturist is to feel closer to the natural world. Stay naked after a shower. Towel dry and go about the rest of your routine naked. Advance to being naked while you’re eating, while you’re cleaning, and especially while you’re relaxing, be it in front of the TV, with a good book or sunning in your backyard.  If you exercise at home, do it naked, unless it's uncomfortable not to wear a sports bra. Remember to respect others' boundaries when it comes to nudity. When you're naked in your house, keep the blinds and curtains closed. Don't sunbathe nude in the yard unless you have a high privacy fence. Being naked in a nonsexual way with your partner may take your intimacy to the next level, plus it means you'll be able to stay naked when he or she is in the house. Discuss whether this is something you could explore together. If your partner isn't into it, ask if he or she would be comfortable with you doing it by yourself.
