I m 20 years old, and for nearly 8 years, I ve had this white callus-like spot on my clitoral hood. Originally, I had cut myself (with a hangnail) and it healed quickly. But ever since there s a thicker callus-like skin. It never hurts, never any mote sensitive than it should be, but it s right where I masturbate. I ve never been sexually active. Should I be worried?
