How long should I wait to text my crush?

Anonymous
To text my crush? I have been crushing on him for a few months now and today I finally asked if he wanted to grab some lunch with me during the week. He said sure and he gave me his number and right now I really wanna text him but I don't want to seem too eager lol. So best time frame for me to wait and text him?

Oops so I think I f*cked up big time then, I texted him like 3 & half hours ago and he hasn't replied yet :/. Suppose if he doesn't text me back tomorrow I'll know for sure what it is or isn't going to be. Oh well you live and you learn.
