POSTPARTUM SEX HELP

I am currently 3 months postpartum. When i gave birth i had 2nd degree tear. I recovered and healed pretty quick. I waited until the 6 week mark to start having sex again and the very first few tries i had a lot of trouble getting wet. We used lubricant and i thought that maybe it was because my vagina was still healing but it’s been 3 months since i became active again and i still can’t get wet. I do get turned on a whole lot but i cannot get wet and it saddens me because before giving birth i had NO PROBLEM at all. Does anyone else have this problem or know how to fix it?
