Lol the good old facets of the good old game ...
its like a game or ritual, step by step :
- initiating contact, for example eye contact, then talking
- getting to know each other
- having body contact, like touching, later holding hands
- making hints and getting closer, roles of pursuit may change a few times
- taking it one step further eventually
You might spend some time with him, and see what you have in common.
You might initiate body contact, like touching his forearm, and signaling you like it if he touches you.
Like not reacting upset if his leg touches yours while sitting on a couch.
Wearing some clothing that craves to be touched could help ... very soft fabrics ... which people like to touch ...
it does not need to be pricey, just knowing and making choices that way could help ...
making some hints then ... from you or from them ...
otherwise it stays in the friendzione.
Then seeing where it takes you ...
Lol its an old game, and you are not the only one starting at this age. There are many cis people who also start if their personalities are a bit more developed.
Have fun, and enjoy yourself
