Metaphorically speaking, if the taste of the sin you have committed does not get bitter- in other words, you still remember and enjoy the pleasure of that sin, it is a sign of keeping distance from Allah Almighty and going astray. Imam Sadeq (peace be upon him) says: lack of bitterness of the sins is the effect of ignorance.
