I don’t feel anything when I insert my fingers in my vagina. How come?

Inside the vagina there are not many nerve endings. It’s far less sensitive than your inner lips or the clitoris. That’s why most women cannot climax by having intercourse and why most women don’t masturbate by thrusting fingers in their vagina. Most girls who want to get excited stimulate the clitoris and/or the area around it. Some like to combine vaginal and clitoral stimulation. When you try some others techniques to stimulate yourself you’ll probably get excited.
