Potty training son

I feel terrible that my 2.5 year old isn’t potty trained. We tried and he went on it once but since then has been scared of sitting on it. So I didn’t push it. He tells me when he poops in his diaper and he even has a designated potty spot that he goes to while pooping. Even when I ask if he’s pooping he tells me yes or he will say mama poop. So I know he’s aware and can communicate. Should I try again? He can also pull his pants up and down as well.
