Great advice so far! I did not potty train my son until he was 3 yrs. 3mo. old. I knew I needed to get on the ball and take the time to potty train him when he was staying dry in his pull up at night! I did 3 days of naked then that was it. Officially no more pull ups. And I was given the advice of very loose or boxer underwear. I actually used the shorts to his Pj's for a week and that worked for us, potty training done! Although, he was also very ready. Every child is different and will eventually "get it"!! As much as you'd like to get him preschool be prepared to put it off for a bit! Do try looser underwear to see if you get better results! Best of luck!! Hang in there!
