Spice it up?

Hello, my husband and I have been together for four years married for three and we have great sex I'm very adventurous. But imwant to spice it up and change it because it has somewhat become routine. I would like for him to be more aggressive and dominant but not full on extreme BDSM. I want to spice it up with new things or positions anything. Except porn he won't watch that with me so that's a no go but anyways suggestions are welcome and appreciated. 😀👌🏻👍🏻
