And continued hatzlocha to you, chaver!
You may doscover along the way over the next few years of clean time, that you have issues in how you approach and view your very own wife. Not just for sex, but as a person you are helping...to your children...and you may discover things in your relationship with Hashem that you may not be able to see now, that are not well.
I am, too. We are 'growing people'.
Sobriety is not the goal, just as the problem is not the real Problem. Gurading Your Eyes will help you stay clean...but the reason you had such a big problem in the first place with self-medicating may never really have been the fault of your penis (or 'yetzer hora'), at all. It may have been more about holes in your inner heart and mind.
No shame in that, chaver. I do not know you, so am not telling, just suggesting possibilities.
Again, continued hatzlocha!
