The question is this: is there any general advice you guys can give to a person like myself who has no romantic or intimacy experience, and most important to this subreddit, identifies as polyamorous?

Oh look at that, a tl;dr right at the beginning! Now for some additional context.

It is tricky to approach any romantic topic without experience. How would I know what romantic love and later conclusions like polyamory without experience? There isn't that much to use except thinking "well, I feel this strong feeling towards some people that most probably would call romantic attraction, but is it really?" For all I know, people talk about love, but it's actually a psychologically harmful. Or what I think might be love really isn't.

That's broad there, but I can apply the ideas to poly. Is it perhaps a bad idea to identify as poly if I have yet to experience anything? It appears to be something great for me, and desirable, but that desire actually gives me frustration. I'm 22 and that seems odd to have had no relationship experience, making polyamory something that much more out of reach. Then again, I may be misconstruing the issue, and it's really just that relationships are tough to find anyway, so I just need a better approach or mindset. Poly does throw me through a loop though, since it is such a minority belief in the first place, sort of making the pool of people "right for me" quite small.

And some context about my beliefs.

There are general beliefs I have already, in particular that I don't like a notion of hierarchy in the sense of primary/secondary, with the primary being given first consideration. Poly is the belief that multiple romantic relationships are possible and good, not that some romantic relationships are more important. I think it defeats the purpose of poly to think in the primary/secondary sense, unless you mean "secondary" as the "getting to know you" stage. If you think I'm wrong, say so! We'll discuss it. That's the point of this thread: I want to hear your advice, including that you think my approach may be wrong.

I mention the intimacy experience in my question because of course it is possible to have intimacy experience with non-romantic interests, although for me, the affection I want to show someone corresponds with the degree of value I have. Then again, I'm not a prudish person (you'd have to take my word for it), so I cannot say solidly that things like sex are a bad idea outside of long-term relationships. I wonder, though, if short term relationships are all that beneficial for me.

If you have advice unrelated to anything I mentioned, that is appreciated, too.
