Another reason how porn destroys you (and no one talks about) is:
It ruins the glue. So I’ve heard, there is strong glue that develops between a married couple who have both had their sexual experiences with no one else except each other. You can call it attachment. You know you wouldn’t be with anybody else because that person was so significant for you emotionally… and this leads to good faithfulness in the relationship. Sounds awesome.
The glue can lose its glue-ness with too much porn. Not that God can’t restore that in grace, but what would have excited you like nothing else in the world now seems unworthy to compare with some of the women you’ve seen out there. Your visual codex is so chock full of images and fantasies and false memories that it’s hard to sort out reality.
Another one is:
If you talk about marrying the right person, I do think there is the right person out there, but not as if it is written in the stars and you might miss him or her if you choose unwisely. The right person is the person that you choose to choose. It’s up to you.
At the same time though, you are directed by your desires. People talk about people with inner beauty, not just outer beauty. The more you look at porn, the less you have an ability to see inner beauty, and the more your desires for a mate are crafted after some false idea of sexual stimulation. Which means it is possible for you to choose “the one” based on criteria you “feel” but that actually misleads you away from your best mate. You may choose to go after one of the most attractive girls you’ve ever seen but miss an even more beautiful person because you could only see the surface.
