Preventing sex from becoming masterbation?

I'm now 1 week clean from porn and masterbation. I'm married and my wife and I have an active sex life (3-5 times a week). The reason for my journey to leave porn and masterbation behind is to help me become closer with my wife and make sex something just between the two of us. Previously, in addition to sex I would masterbate most days, this has gone on for years. I've realized now how much that aspect of my life was impacting sex with my wife which is why I've decided to stop.

So, my question for some of the veterans here in the nofap space (or anyone with thoughts) is now that I've given up masterbation how can I prevent sex from being that replacement. I'm not sure I'm expressing this clearly so as an example I woke up this morning horny and in the past I'd just masturbate before starting my day. Since I'm trying not to do that I instead had the thought that (without being too graphic) maybe I could convince my wife for a quickie or something like that. My desire wasn't about having sex as a couple but instead I just wanted a release.

I think that's the line but I'd like to get other opinions here from guys in similar situations. What should I look out for? How do I know when my desire for a more fulfilling and committed sex life might be in influenced by other desires? I want to feel strong desires and urges for my wife and I want to express those sexually but I don't want it to be meaningless or focused on just getting a release.

Hopefully this makes sense. I'm honestly curious to hear other's thoughts on this.
