Boobs sensation

Hey chicas... so.. I had a baby and breastfed him for about 9 months. My boobs used to be so sensitive and I would get turned on so quickly with the slightest touch, now, not only they sagged and look nothing like before, I’ve lost almost all feeling in them and my nipples .. does anyone know if it comes back in time or if there’s something I can do to get at least part of that feeling/sensitivity back? Sex is not the same .. x ;(
