Video Introduction

        Anal Crisis refers to the thrilling feeling of overexpansion during anal intercourse, and the urban legend that it will immediately collapse after being stretched exaggerates and exaggerates the urban legend of permanent relaxation and incontinence. The overall theme is a hard-core science popularization theme that warns about the risks of anal sex and reveals the truth, playing on the fear of it will collapse immediately. Sex science: Normal anal sex will not cause permanent scrapping. The anal sphincter has extremely strong elasticity and resilience. With moderate, gradual, large-scale lubrication and relaxation, it can return to its original state within hours to days after expansion. Long-term and frequent roughness (such as fisting, large toys without lubrication) may cause sphincter relaxation, mild incontinence, or worsening of hemorrhoids. Practical tips: defecate + enema cleansing beforehand, use progressively sized toys, plenty of water-based/silicon-based lubricants, insert slowly, communicate to stop at any time; do Kegel exercises afterward to strengthen the sphincter muscles. Most people can maintain firmness even after playing with their anus for a long time. The key is to proceed step by step + be hygienic and avoid extreme play.
