Answer:
Depends on the person.
Explanation:
But, when it comes down to it, don't let yourself mold into what other people expect from you. If the person or people you like want you to act a certain way, don't change yourself for them. Be yourself. People say it all the time, but it means a lot more than everyone thinks. Make the first move. Flirt. Ask them to hang out. Ask them on a date. Do whatever you want, but keep you and them comfortable and feeling safe.
