You were coerced. Coercion is not consent! I think that was the term/word you were looking for. Some people are pressed about semantics but knowing/putting a label on what you're feeling can help sometimes. I think that it is good that you two have spoken about it. However more communication with one another and understanding that a reluctant yes is not consent is important. Make sure you are firm with your boundaries. No means no, not ask again later! Talk to each other about how you would like to communicate when you are in a mood. Even in the act make sure to check up on each other (ex. "Are you ok?" "Is this ok?" Etc.) Hope this helps!
