His and Her Health

My partner and I used to have a great sex live and she loved oral sex. However, in the last few months her clitoris has become awfully sensitive, so much so that i cant even touch it at all. It never used to be a problem at all, but now i cant even touch her clitoris without her flinching. She says that she doesn't know why, but it really makes me feel like she just doesn't want me to touch her. Could there be a reason for this? is there anything to use to prevent it?

any help or advice would be greatly appreciated.

If her clitoris is that sensitive she should see her GYN for an examination.He/She could diagnose her and treat her .There could be several reasons for this condition.Only a doctor can diagnose the problem on examination.
