It’s my first priority to serve you.
Thanks for providing more information.
Well as you describe,possible causes may include
Uterine prolapse occurs when the uterus sags or slips from its normal position and into the vagina
Lack of lubrication and foreplay can be contributing factors.
If your symptoms are persistent then a pelvic examination by your gynecologist should be considered.
In the meantime you should try Kegel exercises.
Avoid constipation by eating high-fiber foods and drinking plenty of fluids.
Avoid heavy lifting and straining.
Try to control coughing.
Lose weight if you're overweight or obese.
Use a lubricant during sex.
If you have any further query then we can discuss it thoroughly rather than give us poor/bad service.
We are here to help you until you satisfy.
