I'm 32 years old, married, and I have sex with my husband 1-2 times a week. Although there have been no changes to our sex lives, in recent weeks I e noticed a distinct hardening of my clitoris. It's become very sensitive. There's no burning, itching or hurting- I'm just suddenly very sensitive. As I said, we haven't increased or changed our routine. Why this hardening and sensitivity all of the sudden? Should I be concerned?
