I don't feel anything when I masturbate.

I'm 17, and for years I've attempted to masturbate...but I never feel anything. It feels no different from touching my arm? (This is only clitoral stimulation.)
I get aroused, and I'm not asexual, but I don't understand why I never feel anything? It's not numb...it just doesnt feel very great? Is there something wrong with me? 
I'm going to a GYN soon to see if something is wrong. 🙍🏾
