Afraid to flirt in public?

Whenever I'm with my crush, it's always in public (walking to class, etc.). I really want to flirt with him to show him I like him, but I always chicken out because I feel awkward about touching him or saying something in flirty in public. I'm fairly comfortable with him so I think I could flirt if we were in a more private setting, but I don't know how to make that happen. What should I do?
