Is it normal that i can't get a boner with porn anymore after having sex?

19 Az male.
So i usually have a knack for jerking it to porn constantly. But recently i had sex a bunch and it was penomenal as usual. Because i havent jerked it for a month and have been having sex instead. I tried to masturbate to porn again but i couldnt get hard. Is that normal that i cant get hard form porn? Must i really get pussy just to satisfy my needs? This makes orgasms a lil harder to obtain.
