It places “choices” at the center, showing that they determine whether we seek “creative solutions” or a “negative existence.” The latter is a euphemism for living without sex. https://www.sexbiomech.com/blog/ergonomics-and-human-sexuality monthly 0.5 2026-03-17 https://images.squarespace-cdn.com/content/v1/694eaab63d4f8f2bd81e9525/63a0ceb7-0110-4743-b046-a72fdf628a9e/DVD.png Blog - Ergonomics and Human Sexuality - Make it stand out Ergonomics can mean making tools to make tasks easier on the body. An example is librarians opening DVD cases. Because many public libraries have large DVD collections, librarians often spend a lot of time each day checking that the returned DVD cases contain the proper DVD. The left image shows a biomechanically stressful way to do it. The stress can even be seen in the figure by noticing the tendon in the wrist bulging out against the skin as the box is gripped by the fingertips. Ingenious librarians developed a simple tool to reduce stress by cutting a paint-stirring stick into an opening tool (right image). The grips necessary on the box and tool are much less stressful on the hand than the technique shown on the left. This is an example of adapting the task of opening the DVD case to the person by introducing a tool. As an aside, the DVD shown is “Senior Sex.” It is an educational DVD that is mainly discussions and interviews with people that normalizes sexuality in older adults, but there are some explicit video clips. Thus, it probably is not available at your local library. If you are interested, it can be accessed online. https://images.squarespace-cdn.com/content/v1/694eaab63d4f8f2bd81e9525/1772215700684-REZBJEZBSMRELV17BY4D/GettyImages-171246845.jpg Blog - Ergonomics and Human Sexuality - Make it stand out Sex partners often differ in height, which can make some sex positions difficult or impossible without modification. https://images.squarespace-cdn.com/content/v1/694eaab63d4f8f2bd81e9525/74d54b68-54bd-445a-b50c-231b3265334c/wedge.jpeg Blog - Ergonomics and Human Sexuality - Make it stand out Wedge-shaped cushion can support the body during sex. It can help align body parts - such as the leg, low back, or pelvis - during sex. They are especially helpful when sex partners are substantially different in height. They are available in various shapes and sizes. https://images.squarespace-cdn.com/content/v1/694eaab63d4f8f2bd81e9525/41569994-f941-4adc-9008-e622593ef81a/line+plot+figure+JPG.png Blog - Ergonomics and Human Sexuality - Make it stand out Reducing the physical demands of sex through an ergonomic intervention can prolong sex life as we age. The orange horizontal line represents the physical capacity required for sex. That capacity could be strength, flexibility, or stamina. This diagram is a “cartoon” that presents the concept rather than a specific representation of one-dimensional physical ability. The ergonomic intervention reduces the demands to the green line. This moves the age where sex stops from “end of sex with no intervention” to “end of sex with intervention.” https://images.squarespace-cdn.com/content/v1/694eaab63d4f8f2bd81e9525/1771543425654-TIRZ7DPZBPEPXBP9WIA2/unsplash-image-LjqARJaJotc.jpg Blog - Ergonomics and Human Sexuality - Make it stand out Humans have a wide range of shapes and sizes. Hand tool design, for example, often uses anthropometric data for determining handgrip sizing. Many sex toys must also be designed to accommodate a wide range of hand dimensions. https://images.squarespace-cdn.com/content/v1/694eaab63d4f8f2bd81e9525/1772216620231-QOUVYR264VIWWBRUOKXS/GettyImages-475821878.jpg Blog - Ergonomics and Human Sexuality - Make it stand out What does sex mean to you and your partner? Examining how important each aspect of sex (emotional intimacy, physical intimacy, sexual pleasure, etc.) is to you and your partner is the foundation of ergonomics in human sexuality. https://www.sexbiomech.com/blog/sexuality-biomechanics monthly 0.5 2026-03-20 https://images.squarespace-cdn.com/content/v1/694eaab63d4f8f2bd81e9525/c45b1695-0ccd-4ff8-a585-9d059355809a/Figure+1-line-JPEG.png Blog - Biomechanics and Human Sexuality - Make it stand out Figure 1.

A cup is placed in the pelvis (a thin piece of metal seated inside the bone), and it is lined with plastic to reduce friction as the hip moves. The pink ball inside the plastic is the “head,” which sits on top of a metal stem that is inserted into the thigh bone. https://images.squarespace-cdn.com/content/v1/694eaab63d4f8f2bd81e9525/0fed0b17-9a98-434d-8652-92d4f1babe95/dislocated+well+lit+3.jpeg Blog - Sex After Hip Replacement - Make it stand out The forces involved in walking and moving force the head up beside the top of the cup. https://www.sexbiomech.com/blog/conflict-of-interest-disclosure monthly 0.5 2026-02-03 https://www.sexbiomech.com/home daily 1.0 2026-03-20 https://images.squarespace-cdn.com/content/v1/694eaab63d4f8f2bd81e9525/db9a6528-d038-4331-8c2d-3456c325b734/blown+up+head.jpg https://www.sexbiomech.com/contact daily 0.75 2026-01-28
