For two reasons, you should be regularly doing testicular self-examinations.

The most common malignant cancer for adolescent boys is testicular cancer. In fact, testicular cancer is the most common form of cancer for men less than 40 years of age. One out of every 250 boys and men will develop testicular cancer; and one out of every 5000 of those diagnosed with testicular cancer will die from it.

When detected early, testicular cancer has a variety of treatments which yield survival rates greater than 90%.

Thus, physicians recommend men regularly doing testicular self-examinations.

Before doing your self-examination, keep in mind…


Most people believe in sexual myths (Nobre & Pinto-Gouveia, 2006; Williams, 1990) — for example, “a woman’s hymen determines her virginity.” Believing in sexual myths often leads to sexual prejudices and discrimination. As a replication and extension of Lucas, Fox, et al., 2019 — who found science-based sex education decreases the chances of a person believing in sexual myths, the present experiment tested if science-based sex education decreases the chances of sexual prejudices and sexually discriminatory behavior from occurring.

Method

86 students (mean age of 24.6 years, SD = 6.5) from three different colleges taking human sexuality courses (Higher Education…


Introduction

Although often publicly presented as a simple, binary (yes or no) phenomenon (Withers, 2019), science is revealing sexual consent to be complex and variable. Part of sexual consent’s complexity is it depending on such factors as gender, relationship status, and types of sexual behavior (Willis et al., 2019). Using a novel, non-binary measure, the present study tested whether people’s judgments of sexual consent depend on biological sex and sexual orientation.

Method

Two-hundred-sixteen freshmen- and sophomore-level college students with a mean age of 21 years (SD = 4.5) served as experimental participants; sixty-three percent identified themselves as women.

Except for premature ejaculation, men suffer from erectile dysfunction (ED) more than any other sexual dysfunction. ED is not a disease specifically caused by aging, nor is it an “old man’s disease.” It affects about 10 percent of men per decade of life; that is, 20 percent of men in their 20s, 40 percent of men in their 40s, 70 percent of men in their 70s, etc. And recent demography studies are reporting greater numbers of younger men having ED. For example, a 2018 poll of 2,000 men found the largest affected age group were those in their 30s, with…


One of these days, I will finish writing a book titled, “The Top Ten Myths about Human Sexuality.” But every time I begin writing this book, I find it impossible to fit all 100+ human sexuality myths people need to have debunked for their health, happiness, and safety, into a single top ten list. I guess I need to write a book titled, “The Top 100+ Myths about Human Sexuality.” In any case, this paper is about one of these top ten, 100+ myths: Menopause causes women to lose their desire to have sex.

Sex is Not About Pregnancy

Here is a brief read about an important topic: Gender Equity.

Let me begin with a question: Out of every ten American women, how many do you think have masturbated either as children or after they have grown up?

(While you are thinking about your answer, I will hum the Jeopardy theme song for background music…)

If your answer is 6, 7, or 8, then you are correct. Give yourself a pat on the back. You are unlike most Americans: Most Americans underestimate the number of American women masturbating. …


Male sexual anatomy is mostly presented only in terms of reproduction, even though reproduction is only a fraction of what drives male sexuality. True discussions of male sexual anatomy must include the concept of pleasure, the greatest part of what drives male sexuality. A simple thought-experiment demonstrates just how great this pleasure is: Ask any adult male to calculate the number of times he has had (and will have) sex over his lifetime, then ask him to divide this number into two categories: (1) The number of times he had (and will have) sex for reproductive purposes and (2) The…


Female sexual anatomy is mostly presented only in terms of pregnancy and reproduction, even though pregnancy and reproduction are only fractions of what drives female sexuality. True discussions of female sexual anatomy must include the concept of pleasure, the greatest part of what drives female sexuality. A simple thought-experiment demonstrates just how great this pleasure is: Ask any adult female to calculate the number of times she has had (and will have) sex over her lifetime, then ask her to divide this number into two categories: (1) The number of times she had (and will have) sex for reproductive purposes…


Although our definitions of sexuality are different from when we are children, adolescents, and adults, we are none-the-less sexual creatures throughout our lifespans. And throughout our lifespans, our health, happiness, and safety are dependent on us understanding sexuality. Understanding sexuality, as understanding anything else that matters, begins with learning words.

This paper is about the first ten sexual words children must learn for their health, happiness, and safety.

Defining Sexuality

Sexuality can be defined as a form of communication, driven by intimacy, to achieve biological, psychological, and sociological fulfillment.

Intimacy and fulfillment are mostly based on a person’s age, whereas…


Humans are a weird bunch. Not knowing the definition of something, rarely stops us from debating, judging, or even doing this “something.”

Take for example, orgasms: We debate their origins and judge others for having them while trying ourselves, to have as many as possible, but few of us can define what they are.

This paper, about what exactly an orgasm is…

SHOULD. NOT. BE. NECESSARY!

By adulthood, we all SHOULD know what orgasms are.

We SHOULD know what brings us pleasure.

Indeed, 21st century American society is pretty good with “allowing” us to explore pleasure, if pleasure is associated…
