Vanilla in Bed

So my boy is a little...vanilla in bed. Basically, he always wants to do exactly the same thing and doesn’t even seem to enjoy it. I’ve mentioned wanting to amp up the passion a few times but he doesn’t seem to get it... any tips?

Also, he seems to have a much lower sex drive than me, but he also masturbates almost every day, even when we have sex. Am I doing something wrong?
