feeling lost

hey guys im new here and i need some advice. i recently started this thing with my partner where hes kind of like a daddy figure to me even though we both are in our twenties. its been really intense emotionally and physically but im not sure if hes doing it right or if im projecting too much from childhood stuff. i feel so vulnerable around him which is weird since weve known each other for years as equals. does anyone have any tips on how to navigate this dynamic without it being toxic? thanks in advance.
