Yes, I definitely think you're onto something as far as it beaded your subconscious level. How you feel about your body, how you feel about your performance, comparing yourself to your partner I think is all relevant.
Maybe ask yourself "what exactly do I want to achieve?" And then go from there. Maybe focus on one small thing. But letting go of those inhibitions about your body I think can be a major player for you.
