i (F23) can't help but feel so shallow. i have been with my girlfriend for 5 years. over the last year or two i've found myself more interested in bdsm and kink. it feels very important to me and my identity. we DO have good sex but i don't feel like im expressing myself fully in the bedroom. i feel very different to other people and what i want in a relationship. other than this our relationship is perfect. she is my best friend. we have a cat together .. i feel this is a 'stupid' reason to break up. but at the same time my intuition is telling me im not satisfied. i fear i have a 'grass is greener' mindset.. and that if i do the the relationship i'll be disappointed with the reality of the situation. i'm also very young and want to live out my fantasies and ideas.. it's a tricky one. i don't know what to do
EDIT: yes i've spoke to her about what i would like to try and if she is open to it. she is very much not open to it and generally has a poor view of kink and bdsm.. and also not interested in an open relationship.
