"What are the flaps in your vagina?"

My boyfriend is a grown ass man (32 years old) and were laying in bed and he grabs my legs and hes like "let me look at it" and im like what? No and hes like "let me looooookkk at itttttt!! Woah what are those flaps? Why do you have that?" Like are you fucking 4 years old? Why say something like that and get me all subconscious about it??? (He was referring to inner labia)
