Sex is not effective in improving the bulging vaginal walls, nor is it likely to restore the bulging vaginal walls. The female pelvic floor is made up of a variety of tissues such as muscles, fascia, and ligaments that work synergistically to maintain the pelvic organs such as the uterus, bladder, and urethra in their normal position. As the connection between the pelvic floor muscles and ligaments becomes lax due to childbirth, aging, trauma, etc., the supportive capacity of the pelvic floor weakens, which can cause the vaginal wall to bulge downward. Transvaginal intercourse does not have the effect of improving the tone of the pelvic floor muscles and ligaments, and does not improve vaginal bulging. Pelvic floor muscle exercise and lifestyle improvement can improve the effect of vaginal dilatation to some extent, and surgery can be used for serious cases. Vaginal dilatation should be standardized treatment under the guidance of a physician, and if symptoms occur, it is recommended to consult a doctor in time to avoid delays in treatment.
