Putting a sex toy in is usually not going to affect the uterus. Because the position of the toy is inside the vagina and not in the uterus, it will not cause any harm to the uterus. However, you must be careful not to put them in too deep or move too vigorously to avoid damage to the cervix. You can use sex toys appropriately, but it is not recommended to use them frequently to make your body less sensitive to “sexual arousal” and sexual arousal becomes more and more difficult. In addition, before using sex toys, be sure to clean and disinfect the toys to avoid gynecological inflammation due to unclean toys.
