How to be a better future partner?

I, (16M) have never been in an intimate relationships; but I always wanted to be in one. Not in a desperate way of course. I dream of having someone to be able to love with all my heart. To spend as much time with as possible. Which is precisely why I wish to learn as much as I can till I find a partner—be it short-lasting or long—after-all knowledge is key. After that, I'll let my future self make decisions, building up experience.

For now I'm trying to learn more about the menstrual cycle and periods so that I can at least take care of my partner when she is in pain. After that I'm quite lost. I know open communication, empathy, and acts of affection is a big factor in relationships, but besides that, I am still lacking in a many things, specifically experience, wisdom (applied knowledge), and most of all, knowledge.

Anything will do: Books; articles; videos; your own advice; and even research papers for things to watch out for!

Thanks in advance.
