Sex after baby

Ok so I’m about a year PP and I have not had sex yet.... Recently my SO and I have been talking about trying again I haven’t wanted to because I’ve been so scared of the pain so I’m 10 month pp how bad will it hurt and is there a chance I could tear again as I did giving birth the pain and re-tearing are my biggest fears is this possible and how bad will sex hurt? I just want to be prepared!
