What are signs that a man is interested after a first date?

If the first date was fun with equal talking, laughing and flirting. A few kisses and the guy referring to future plans and saying “we” statements. What is considered normal and appropriate communication after the first date. I am not very familiar with how functional and emotional healthy males behave. Some pointers would help to have a clear idea of understanding reasonable male behavior.
Thanks!!!
