Reasons why underwear gets stuck in the crotch when walking

Underwear sticking in the crotch when walking may be related to factors such as inappropriate underwear size, material problems, body shape changes, or friction during exercise. This situation can easily lead to local discomfort or even skin damage, which requires targeted adjustments.

1. Underwear size problem

Underwear that is too small or too large may cause the crotch to get stuck. Underwear that is too small can tighten the groin and compress blood vessels and nerves ； Underwear that is too large will shift and accumulate when walking. It is recommended to measure the waist and hip circumference before choosing the corresponding size. For briefs, pay attention to the crotch depth, and for boxer briefs, pay attention to the tightness of the leg circumference. Pure cotton material has certain ductility, but too low elastic fiber content will also affect the fit.

2. Improper material selection

Chemical fiber underwear has poor air permeability and tends to stick to the skin and cause friction after sweating. The edges of decorative fabrics such as lace may scratch sensitive areas. Moisture-absorbing and sweat-wicking fabrics such as modal and bamboo fiber are preferred. It is recommended to choose pure cotton interlayer for the crotch area. When exercising, you can choose quick-drying underwear with breathable mesh to reduce fabric shifting due to sweat.

3. Effects of body shape changes

Gaining weight will cause fat accumulation on the inner thighs, making the original underwear crotch narrower. The forward tilt of a woman's pelvis during pregnancy will also change the stress point of her underwear. Testicular varicose veins in men may cause changes in scrotal volume. It is recommended to re-evaluate the size of underwear every six months, and obese people can choose high-waisted models to disperse pressure.

4. Increased motion friction

When walking or running for a long time, repeated friction between the legs will cause the edges of the underwear to curl. Special sports such as cycling require seamless or three-dimensional underwear. Diabetic patients have reduced peripheral nerve sensitivity and are more likely to cause ulcers due to friction, so they need to choose underwear with no seams.

5. Pathological factors

Skin diseases such as tinea cruris can cause local skin thickening and change the friction coefficient. Inguinal hernia may cause abnormal bulge, so you need to choose loose-fitting medical underwear. Some patients with gynecological inflammation need to change underwear frequently due to increased secretions, and a humid environment is more likely to cause discomfort. It is recommended that patients with related diseases seek medical treatment for the underlying disease.

For daily use, you should choose fitted underwear with a crotch width of 3-5 cm to avoid shrinkage caused by high-temperature drying after washing. Before wearing new underwear for the first time, you can soak it in softener to reduce the hardness. If you find that the crotch is stuck when walking, you should adjust or replace it immediately. Special groups of people can choose customized underwear, and pay attention to the clean and dry perineum. If persistent skin redness or pain occurs, timely examination is required.
