You do not need more hours; test whether attention makes you enjoy them more.

You are asking for more time because it is easier than admitting that attention feels burdensome and some conversations do not interest you. You want to find out whether listening changes that, but have not decided what you will do if it does not.

Are you asking for more hours to avoid giving real attention?
More hours feel easier to ask for than real attention.
Do you still want to be present when their topic doesn't interest you?
Not always; I’m less interested in them than I want to admit.
Would you still want more time if it didn't change how you feel?
No; I want more time only if it changes how I feel.
