Love Languages . . . How?

So my love language is touch, and then time. Everything else is extremely low on the list. I've known this for forEVER. But I've never been able to figure out how to deal with it in our society.
I mean really. If you hold hands with someone our society assumes: dating/in an intimate relationship.
If you hug someone for more than 1 second, society assumes: dating/in an intimate relationship.
Basically if you touch somebody, society assumes: "OOOOOOOOOOH they're flirting!"
Now this isn't *quite* as bad in the non-christian culture I personally have experienced. But it is a *huge* problem for those of us who speak love with touch in the christian community.
Everyone has this idea that if you are touching, you are in, or you want a dating relationship with that person.
So we have a bunch of people who's love language is touch and we aren't allowed to hug people, touch their shoulder with a reassuring pat, be excited to see people and greet them with a hug, hold their hand, basically we aren't allowed to speak our love language.
I know for several people there is a line that makes them super uncomfortable if you cross that line. Sometimes it's a hug sometimes it's a handshake, sometimes it repeatedly poking someone. So as a touch person, I try to respect those lines.
But I literally. Don't. Know. How sometimes.
How do I show you that I love you, even if it's just as a friend, and how do I know you love me as a friend.
I try super hard to utilize the other love languages to try to communicate that you are important to me. But sometimes my heart just feels like screaming out of frustration because I can't speak my love language.
It's especially difficult when I'm around people I haven't seen forever because I want to hug you and not let go! I am SO beyond excited to see you that I just can't hold it in. and sometimes that comes out as incessantly (gently) slugging you in the arm. patting your head, poking you. and it's not because I'm trying to flirt at all, it's just because I love you. and you're FINALLY back in my life, and I'm SUPER excited.
But people have told me that doing those things is not okay, and it's crossing a line, and yea I can see that. But what am I supposed to do?
Nobody has ever given me an alternative other than just "do nothing", and that just kills me. I love each and everyone of my friends deeply, and for me, telling me to do nothing feels the same as saying I can't I love them. Goodness if you even say "I love you" in society, and especially the christian culture, then everyone in your life assumes you've got a "thing" for each other.

So I guess this post is about two things: 1 venting. and 2. asking you a question.

So my question for those of you who are not touch people:
What are some ways that I can tell/show you I love you without
- acting like an idiot
- making you uncomfortable

I honestly don't know and I've been looking for the answer for years and I've still come up with nothing. So I need your help. How do I be myself, and show that I love you as a friend in a way that you're okay with?
