It is possible that coitus may be affected after vaginal wall expansion surgery. The methods of vaginal wall bulge surgery include anterior vaginal wall suture, suburethral folding, and paravaginal repair. Anterior vaginal wall suturing and suburethral folding involve folding and suturing the muscles of the anterior vaginal wall, the bladder surface fascia, and other tissues to restore the bulging vagina to its normal position. Paravaginal repair involves separating the walls of the vagina on both sides of the bulge and restoring them, one by one, to the level where the pelvic ligaments are attached. All of these methods may cause discomfort such as urinary retention and difficulty in urination after the surgery. There is also the possibility of difficulty in sexual intercourse after the surgery due to improper recovery, so it is recommended that you seek medical attention if you experience discomfort after the surgery.
