Do I make my son have drum lessons?

Ok, I bought my 8 year old son a proper drum kit for Christmas and he really enjoys playing on it. I’d like him to have lessons so he develops proper techniques and learns how to play. He is very reluctant to say yes to lessons but won’t explain why he just says “i don’t know why” I think he is nervous but I’ve reached an impass with him, I’ve taken him to meet a teacher who is really good but he won’t commit to lessons. My son is also dyslexic and I figure it might be good for him all round to have a hobby but how best to proceed?
