Is It Normal for your woman not to want to suck your dick

Eh id say its normal, personally i love the idea of sucking someones dick or eating a girl but im just not into getting a bj in return or whatever but i love a rimbjob. I guess what im trying to say is its all just a matter of preferance its completely understandable why she dosnt want to i get it i do. And for alot of women they just are not that into sex same with guys tho its less common for guys i believe
