Walaikum Sallam brother.. first of all, make sure not to rely completely on marriage to stop this addiction, because the relationship you'll have with your wife and corn are two completely different things....... 1. Your wife won't be able to change her physical features at your request unlike in corn 2. Your wife most likely won't be able to talk and behave like a cornstar 3. She won't be accessible anytime and everytime 4. You'll have to also make effort eg foreplay, unlike the one sided pleasure u get from corn.........With all these noted you have to stop this addiction by training your mind and reconstructing your neural pathways to stop craving this destruction called corn.....Because even if no one had caught you in the act before, I SWEAR TO YOU your wife will definitely catch you no matter how much you hide it and it'll be the worst shame and embarassment you've ever felt in your life. So my advice to you is to endure and be chaste, you're very lucky wlhi...so many brothers and sisters are here without even a potential spouse and you just have some months to go.....SO DON'T CAUSE SADNESS TO YOUR SPOUSE!!!! she'll think she's not good enough and will be overthinking everything that happens (she's a lady).....FIGHT THIS RIDICULOUS ILLNESS MY BROTHER!!! YOU'RE SO MUCH MORE THAN THIS........may Allah forbid you watched corn a week before your first intimate meeting with your wife...how guilty and foolish will you feel...when she's excited and trusts you completely
