Are me and my boyfriend boring?

So we've been together for a couple of years and everything is perfect - it's just that we never seem to come up with anything to do! We like going out for dinner and make sure we see our friends a lot (both together and separately). But when it comes to thinking of stuff for us do on the weekend or day off we can just never think of anything! Does that mean we're boring?! We're quite homely people - so like staying in and making dinner and watching sitcoms. But it would be good to do something different occasionally. Any ideas?
