Sex after baby?

Galllsss i haven’t had sex in nearly a year, because I broke up with my baby’s dad when she was 2 weeks old, (I lost my virginity to him too) 8 months later I got a new boyfriend, but when sex eventually happens I’m scared that it’ll hurt after, haven’t had sex in so long? And after birth I also had 2nd degree tearing😒 any advice🤔
