Thing is your explanation actually does the opposite of saying you don't feel entitled. The fact that you use the idea that "I would do it for you..." this actually is saying to the partner exactly this: "since I would do this for you, you are obligated to behave the same" it is expecting that one would conform to your behavior simply by the fact that it's your view, your values and your perception of how things should be. that is an attempted manipulation of another person based on your entitled feeling that because you do something others should do the same. The definition of entitlement.

Whereas in a balanced and healthy relationship you are able to accept that others are different, even up to your actual partner. No one is ever obligated to think act and feel exactly as you do. Turn the tables, how about you being obligated to not desire sex as much because your partner doesn't?
