"Self-denial" is a bit of a loaded term. It strongly implies "denying a part of yourself" as opposed to "denying something to yourself". Someone who chooses to be monogamous even though attracted to more than one individual isn't denying that attraction any more than someone at an all-you-can-eat buffet who chooses to consume a sensible, nutritionally-balanced meal. Or someone who chooses to focus on a specific set of crafts and hobbies rather than diving into every new interest that comes along.

It's good that you're happy about the particular life choices you've made, but given that several readers have had the same reaction I did, you might want to figure out if you could describe it in a way that doesn't imply that yours is the only honest and rational choice.
