Numbness inside vagina during penetrative sex

Patient: I have been sexually active with my boyfriend for 2 years now, and we have had perfectly normal and functional sex. However, the past 2 times we have had intercourse has resulted in a numb feeling in my vagina. The outside of my vagina can feel sensation as before, but I can now feel absolutely no sensitivity through penetrative sex, not even a pressure. The inside of my vagina feels entirely numb, which makes sex highly unpleasant. I have been on the contraceptive pill Ovranette for many years now, could this be the cause? Or is there something wrong with me? PLEASE help!
