Hello Openrelationship?
First, feel free to ignore the question about resources. It doesn't seem particularly relevant to you, from your original post. Sorry Hanky incorrectly assumed your gender, new members don't always know where to see the information people put in their profile.
I’m honestly just seeking out advice on how I can start to get better at my view when it comes to thinking about intimacy and how others have learned to share time in the relationship.
As for sharing time, this can be connected back to what you believe a romantic relationship should look like, which is largely based on what you either saw, or didn't see, as a kid. I grew up in a mono household wherein my parents would almost without fail share an early evening meal but at least once a week (frequently more) one or the other would head out to whatever hobby activity was happening that night. They did this separately, time to connect with their own friends and interests (and have time away from being a parent!)
I think of sharing time with others outside the relationship as healthy for any relationship; being "joined at the hip" as a couple is not romantic, it's stifling. If you have beliefs around how much time people in a relationship SHOULD spend together, this might help:

As for your views around intimacy, again it could be worth examining their source. What were you taught about any form of intimacy (from conversation to shared silence to sex, and any other forms you can think of)? What beliefs do you hold and why?
You wrote that you need a lot of closeness and emotional bond to feel secure. That sounds like you're relying on your partner to make you feel secure rather than on yourself. Perhaps read: Polysecure: Attachment, Trauma and Consensual Nonmonogamy

This could help you examine what it is to feel secure within a poly context.
I get to want to be close to someone in other connections too rather than just the one so I’m not putting it all on her.
How are your friendships and family ties these days? Please don't feel like you, too, have to try romantic polyamory to have a variety of fulfilling relationships. I know you have said that logically you are completely understanding that having multiple of any type of relationship doesn't diminish each of them, but:
(Like I said before, I’m great at thinking this way until I have to think about intimacy with someone else or feel like I’m not getting time or affection with my partner)
The time issue in poly is often dealt with through clear scheduling of date times. Phones away, no external communications (emergencies withstanding) and a deliberate choice to share intimacy of whatever form during that time. This is separate to daily living stuff, especially if you live together. Do you really need "date night" seven days a week? No? Because you need a life outside the relationship, too? Cool. Then what is your secure number?
As for thinking about (her) intimacy with someone else, again, what were you taught about that and how much is actually relevant to you? I grew up Christian and with an ownership model of matrimony from dogma. My parents were far more relaxed than the church was and when I declared to my mother (when I was about 14) that I wasn't going to have sex until I was married, she replied, "you might want to rethink that." And left it there. That one sentence removed any future guilt once I did decide I was ready to start sharing sex with people.
You may not have an overt sense of ownership over your partner, but western society has conditioned almost everyone into having a mononormative view of relationship structures. It's tough to go against the flow, obviously. Be patient with yourself.
I hope something in here helps a little. Try those links and feel free to keep asking questions.
