sex after first child

Ashley
So I had my baby about 3 months ago and just had sex for the first time since I got pregnant .... It's not that it hurt or that I didn't have the libido.
It was just my Vigina was not nearly as sensitive as it use to be... It's almost impossible to peak. 
Will this be permanent? 
Will I ever enjoy sex again
Have you ever had this problem?
Any advice?
