In actual fact, masturbation has many health benefits.
For women, masturbation can help prevent cervical infections and urinary tract infections through the process of “tenting,” or the opening of the cervix that occurs as part of the arousal process.
Tenting stretches the cervix, and thus the cervical mucous. This enables fluid circulation, allowing cervical fluids full of bacteria to be flushed out.
Masturbation can lower risk of type-2 diabetes (though this association may also be explained by greater overall health), reduce insomnia through hormonal and tension release, and increase pelvic floor strength through the contractions that happen during orgasm.
For men, masturbation helps reduce risk of prostate cancer, probably by giving the prostate a chance to flush out potential cancer-causing agents.
Masturbation, or touching one’s own genitals for pleasure, is something that babies do from the time they are in the womb. It’s a natural and normal part of healthy sexual development.
