Hey there! Welcome!
I also struggled a few months into marriage, I actually almost destroyed my bedroom life with a Hollywood perspective that was false.
I truly had a spectacular relationship with my wife right away bh,(which I almost blew) but I can't compare it at all to now, after I started to work on myself on GYE.
A woman doesn't have to know she's not your only source of sexual interest to feel it. It's like an invisible toxin. When your wife is truly your sole interest she will feel it.
In addition since you will feel so much better, your connection will be more open and honest because you are living an honest relationship. You and her will feel a tremendous difference. You will be able to love her more and properly, and she will feel it.
Now is the most important time to truly work on it, because you are building the very foundation of your marriage, and the relationship that will sustain the rest of your lives. If you do it properly your whole life will be different. If it's done at a later date, you will have to start undoing and redoing things which if possible is much more difficult.
Now is the time! Stick around and learn the truth about lust.
