First of all: How do you manage to smell your dick?
Second of all: I think it is normal that your dick is more clean and has a better smell shen you stop ejaculating. Ever seen cum? It's disgusting. You want that pouring out of your dick every day?
Washing after every ejaculation doesn't solve the problem. I noticed myself whenever I ejaculate, my whole genital area starts to sweat more and give a smell that is similar to the one of cum. Again, washing doesn't entirely solve the problem here, so I am stuck with smelly underpants the rest of the day.
I believe that there are certain pheromones being released through your glands which are responsible for the smell. If you stop fapping you will not have this problem again. I am already at 30 days anon, you can do it trust me, I believe in you.
