Hey there.
There is nothing wrong with you! If you don't feel anything, you don't feel anything - nothing wrong with that. Have you talked to your boyfriend? Told him how you feel? Some times you cannot get sexually aroused just by touch. Foreplay is sometimes needed.
I will say this again: talk to your boyfriend and see if you guys can do other kinds of things to stimulate your sex drive, like foreplay.
It'll be okay, do not feel inferior about this.
