Unpacking masturbation: Sex Ed #14

Key Concepts:

• Masturbation: Self-stimulation of genitals for sexual pleasure.
• Sexual Revolution: A social movement in the 1960s promoting sexual freedom and acceptance.
• Dopamine and Oxytocin: Hormones released during orgasm that can reduce stress.
• Endocannabinoids: Neurotransmitters that regulate sleep, pain, and immune responses.
• STIs: Sexually Transmitted Infections.
• NoFap/No Nut November: Movements promoting abstinence from masturbation.
• Semen: Fluid containing sperm, historically considered a "vital fluid."

1. Definition and Prevalence of Masturbation

• Masturbation is defined as stimulating one's own genitals for sexual pleasure.
• It's a common practice throughout life, not exclusive to humans.
• Surveys indicate that most people masturbate, regardless of gender, sexual orientation, age, or relationship status.
• It's a normal part of human sexuality with individual variations in practice.

2. Historical Context and Evolution of Sex Toys

• Evidence suggests humans have been masturbating for as long as they've existed, supported by prehistoric rock paintings.
• Archaeological findings reveal sex toys dating back to the Han dynasty in ancient China.
• In the 1960s, Gosnell Duncan created the first silicone dildo to address the needs of disabled individuals, who were often excluded from the sexual revolution.
  • Duncan's innovation addressed issues with existing rubber sex toys (harsh smell, inability to be washed, melting in heat).
  • Silicone became a standard material for sex toys, improving hygiene and usability for all.
• The sex toy industry has diversified to cater to various interests, sexualities, and abilities.
• Safety guidelines for sex toys:
  • Use condoms for shared toys.
  • Use only objects specifically designed for sexual use.
  • Ensure toys inserted anally have a flared base to prevent them from getting stuck.

3. Potential Benefits of Masturbation

• Reported benefits include relaxation, anxiety and pain relief, and improved sleep.
• Scientifically, these benefits may be linked to the release of dopamine and oxytocin during orgasm, which counteract cortisol (the stress hormone).
• Masturbation stimulates the release of endocannabinoids, regulating sleep, pain, and immune responses.
• Potential long-term medical benefits:
  • Increased blood flow from regular masturbation can maintain genital tissue health for people with vulvas.
  • More frequent ejaculation may be associated with a lower risk of prostate cancer for people with penises.
• Masturbation can help individuals explore their sexuality, understand their preferences, and build sexual confidence.
• Studies show that single women who masturbate report greater sexual satisfaction in partnered sex and have a more positive self-image.
• Masturbation offers these benefits without the risk of STIs or pregnancy.

4. Cultural and Historical Perspectives on Masturbation

• Historically, attitudes towards masturbation have varied.
• Ancient Sumerians and Egyptians included masturbation in their creation myths.
  • Sumerians believed a god created the Tigris and Euphrates Rivers by ejaculating.
  • Egyptians believed a god created the universe through masturbation.
• Ancient Greeks viewed masturbation as a normal bodily function but associated it with lower-class citizens.
• Many religions hold negative views on self-pleasure, citing lust or the belief that sex should be exclusive to marriage.
• In the 1700s, Swiss doctor Samuel Auguste Tissot popularized the idea that semen was a "vital fluid" that should only be used for procreation.
  • Tissot and others falsely claimed that masturbation led to weakness and infertility.
  • They also incorrectly believed that semen originated in the brain, leading to claims that masturbation lowered intelligence.
• In the 18th and 19th centuries, masturbation was falsely linked to disease, maladjustment, and insanity.
  • Victorians used anti-masturbation devices to prevent erections.
  • Dr. John Harvey Kellogg advocated for bland, fiber-rich foods (like cornflakes) to suppress sexual urges.

5. Modern Myths and Misconceptions

• Modern myths persist despite the lack of scientific evidence.
• Movements like NoFap and No Nut November encourage abstinence from masturbation, falsely claiming it increases testosterone.
• There is no scientific basis for claims that masturbation causes physical or psychological harm.

6. Conclusion

• Masturbation is a normal and healthy part of human sexuality.
• There is no need to feel shame or embarrassment about it.
• Myths about masturbation causing harm are unfounded.
