A female led relationship (FLR) is not about your kinks. It’s about her.
A Dominant woman is not a fetish dispenser, she is a Goddess to be obeyed.
So you have a thing for feet? Great, so do many men. Maybe one day, when the time is right, you can have an open chat with your Dominant about it.
Until then, focus on obeying her, pleasing her and making her happy. She will explore your kinks, if she wants to, on her terms. She’s much more likely to if you are dedicating your life to serving her. Embrace her leadership and immerse yourself in service.
