<human>: I (18m) have very little experience that I remember about with platonic friendship with females. I had friendships with girls as a young lad back when all that mattered for friendship was being nice. Middle school being the weird time that it is, I "forgot" how to socialize with people, not just females, so I pretty much only socialized with my childhood friends and a handful of others. 

Now onto the reason for this post. I have this friend, her name can be Katie(17f) for he sake of anonymity, and she is the only girl that I talk to regularly. We have been friends for just over a year, and I hang out with her like 3 times a week, but I think our relationship is kind of strange. Thinking about our relationship, some things don't feel "normal". For example, we hug way more than I feel is acceptable for a normal platonic relationship, which I justify by thinking that I would have to stop hugging her as I do now were I to have a romantic girlfriend. Its not just the hugging that confuses me, I guess I feel our relationship is way more "physical" and intimate than I assume is normal. 

My question is, how should a regular platonic friendship be?

Give me the gist of the text in a nutshell
<bot>: I feel like I have a weird relationship with this one girl, and it confuses me on how a normal one would go.
