Potty Training

Patient: My son is 3 years old and he is potty trained fully with some mishaps at night by him not waking up to pee at night. The main problem is the aiming at the toilet. A couple months b4 we started potty training his doctor said that he ripped his hole by tugging at it.I was fine til i started noticing that when he pees it sprays everywhere even when i try to help him. I’m lost and i don’t have a clue what to do
