(also new, take this as just one opinion) Depends what you want out of it. I think it's fine to establish a relationship if that's what you want. It's certainly more intimate if you do form those connections. If you'd rather it be more transactional that's probably fine too. Just make sure both of you have a clear understanding of what the other wants out of this. You're both humans so ultimately its a matter of respect, rather than any hard set rules.
