I think you are BSing yourself you were/are interested and she was too at least at one point. The problem is most people will do more to avoid pain then they will to gain pleasure. Your fear of rejection most likely cost you a chance of recon.
If you truly couldnt care less like you indicate, when she said to you to come into her room if you want because you seen her naked 1000 times. Why did not playfully say I would love to see you naked right now? Totally acceptable response at that point.
Its the mans job to lead, especially in the bedroom.
