Although five years may seem young, in cat years he's actually a teenager now, so that play probably doesn't interest him anymore.
You won't be able to teach him to play if he's not into it - and if he prefers cuddles then all the better!!! Sounds like such a sweet boy...
I usually find that my kits like everyday things around the house to play with much more than actual toys - you know, scrunched up paper balls, hair elastics (especially!) etc. Try getting out a box, even my Sunday, who wouldn't play if her life depended on it (too busy sitting around looking pretty and headbutting everything she sees...lol) will go a bit spazzy when there's an empty box around.
Oh - and have him in the room with you when you are trying to put fresh sheets on your bed - I have never, and I do mean never, come across a cat that can stay calm when this is happening! It might put him in the mood, so to speak
