I bought a potty when DS was 2y1m and the very first time he sat on it he did a wee! Easy :) Then we would just talk about it, and sometimes he'd sit on it, and sometimes he wouldn't.
I wasn't in any rush to potty train; DS had (has?) language delay and I was much more focused on working on that, and I didn't think he had the capability to communicate with me about needing the loo etc.
Plus we have moved house twice in the last year and have had quite a lot of other change. So I didn't want to start until we had a period of calm.
So last weekend, with DS at 3y2m I started, and after the first morning of 8 changes of wet pants
, and then a poo in his pants which shocked him, he quickly got used to the idea that the potty/loo was the way forward.
Helped enormously by his Thomas obsession; every pee and poo on the potty/loo got a gold star on the Thomas reward chart, and a Thomas sticker. Every 10 stars got a new Thomas train (thank you toyshop.com for being half price at the moment).
He's had no accidents for 5 days, and even more amazingly has had dry nappies in the morning 4 out of the last 5 days when prior to last weekend his nappy would be bursting in the morning, often leaking out to wet the sheets etc.
So whilst it's early days I'm feeling really pleased that I left it relatively late and it's clicked so fast. I know all children are different and for many reasons may not "get it" so fast. But from what you describe I would say your DS is too young/not ready.
PS some children have a fear of the loo as it's so big, we've used one of those portable potty/training seats . It's worked well.
Good luck.
