Pp sex

Tuesday i get the official okay to have sex for the first time since having my baby and im completely terrified of trying again. (dr. said we could try so long as i felt like i could do it) the few times that we (my Fiance and i) attempted to try, i couldn't have him bearly go in because it hurt so much and just put a halt to everything. I want to but im scared and i want my hubby to be satisfied since we havent had actual sex in months. Is it wrong for me to be scared to get the offical okay? how do i help make things less painful once i get the okay?
