Listener question: how do I ask for what I want when I don't feel I deserve it?

I am in a lot of self-inflicted emotional pain and hoping maybe as a topic for one of your podcasts you could talk about conditioned beliefs around sexuality and self-worth. I have been in a relationship with someone for nearly a year and theres not been a declaration of love or wanting commitment from me from him but we are exclusive. I think that because of my conditioning in childhood I have been unable to ask the question and ask for what I need from him and also believe my inherent worth to him is in the bedroom. But are all those just thoughts and not true? Then why does it feel the relationship manifests that way? I don’t know whats true anymore and feel very stuck in what to do around my communication with him regarding this and our relationship moving forward. How do i get unstuck and ask for what i need when i dont feel i deserve it?
