It depends on the couple and how your wife feels about it. Does it ever impare your ability to have sex with your wife? I have no issue with porn (I am a woman) me and my bf will watch porn together sometimes as a way to change up our sex life. I use porn when bf isn't around, bf does the same and we both are aware of this and are comfortable with this and it never impares our sex life together, nor does it upset me . If it is affecting your relationship with your wife, or you are hiding it from her then yes I would re-evaluate what you are doing and stop. If it is imparing any part of your life then it is an unhealthy obession. Otherwise I am not sure what you are asking with the post. Wishing you the best -Typo
