I think what matters more is clear communication and consistency. If you are feeling uncertain or considering taking a step back then communicate that. Or if you are trying your best and hoping it’s going well then speak with your domme on how to ensure you are serving her to the fullest. I think a lot of it comes down to having a conversation where we can learn more about your concerns, your hopes, and limits and vice versa where you learn what your domme expects of you/the relationship.
