"Look how he's always flirting with every woman he meets. I'm so tired of having to look at his white teeth and slicked-back hair."
First of all, is "having to look at" the most natural thing to use here? Would it also be natural to just say: "I'm so tired of looking at..."?
Secondly, if no one is forcing the one speaking to look at him, why is it still natural to say "having to look at"?
