My friend gets excited when she stimulates her urethral opening. Mine is insensitive. How come?

With some woman the urethral opening is so sensitive to stimulation that they have given it a special name: The U-spot. But the sensitivity of the different parts of the vulva varies greatly from woman tot woman. Research has shown that there is a lot of diversity in the way the nerve endings are distributed throughout women’s genitals. That’s probably one of the reasons no two girls masturbate in exactly the same way. So it’s perfectly normal if your girlfriend’s urethral opening is very sensitive, while yours isn’t. That’s why it’s important that you learn to know your own vulva and discover which parts are most sensitive. You can then use this knowledge later when making love.
