My Fluids ???? TMI

I'm a first time mom and before I got pregnant...and me and my boyfriend did anything sexual I would easily get wet..but since I was pregnant it's been extremely dry and I still find him very attractive after 3 years..I gave birth 4 weeks ago..will my vagina go back to normal ?? he feels like I'm not attracted to him since my vagina didn't  get wet will I was pregnant and sex is way easier with my own wetness
