Plate asked post sex when my first kiss was (we v young, I’m her first), I kissed her and told her 5 seconds ago. I kept avoiding the question but she kept asking it and pestering me. I heard somewhere that you shouldnt talk about your past so I didnt end up answering.

Question is, can I answer and will it really decrease attraction to tell her (It wouldnt be her)? What happens if she brings it up again? What do i say when she asks me why I dont talk about my past?
