Is it normal to wonder how to broaden your sex life

So , My bf and I are both big, not huge but big, our sex is kind of dull, I give him bj until he almost cums then he sticks it in and finishes , We are overweight and it is depressing ot him I know, if we coudl finda differnt way other than doggy style and bj's we could get a little more active because i have a really really big sex drive.
