I like this guy I who works at a coffee shop, the first time I met him I think he caught me checking him out. A few days later he initiated a conversation and we have been talking casually since. Today I touched his tattoo and rubbed my finger gently on his arm and asked him to come hang out with me when he gets off work. we talked for a little while and we exchanged numbers. But I'm not really sure if he is gay and if he is attracted to me either, I have a hard time telling if a guy is gay or if he is flirting with me. What must I do?
