I've had genital numbness for over a year, what could this be due to?

I've been on abilify for almost two years. I am now off the medications. When I started taking it, I experienced a numb clitoris and numb vagina. Could this be due to the medications, or is it a nerve problem, has anyone else experienced something similar? My psychiatrist says it's not because of abilify, my gynaecologist says it is.

I suspect Abilify ,it’s a strong drug
