I’m a man, and I’m assuming you are female. I’m going to answer it from my perspective as a man who has struggled with porn, lust, etc.
– I would say it’s wrong because you are objectifying yourself and potentially causing your spouse to objectify you. When looking at sexy pictures (even of one’s spouse) it often removes the imagination, emotion, etc from the man. He will often focus all his attention on one part of the picture, which will lead to lustful thoughts and perhaps sexual sin.
Also, over time, it can cause him to become a selfish lover due to sexual addiction to lust.
If a spouse wanted to do something to make her husband look forward to an special evening together, simply saying something (even something sexy) would be much better because it would trigger more of an emotional response instead of a purely lustful response.
I pray I’m making sense.
God bless!
