Men answer: how long do you wait to make it official?

It's been a long time since I've been in a relationship so I've completely forgotten the general "rules" of dating, so to speak. I just want an idea of how long men wait to make it official with a girl they've been seeing? Months, number of dates, etc. Things are getting pretty serious with me and this guy I've been seeing for the past couple months. I'm not one to rush things, and I don’t think he is either. If it matters I'm 24F and he's 32M.
