What Do You Mean By *Take it Slow*

I've noticed a few OLD profiles that indicate the guy (yes, the guy) wants to take it slow. They say things like "let's be friends first, and if there's more, then great." Or they say things like "I want to get to know someone before moving forward to anything else."

You get the idea. However...what does it mean? Endless texting until that person decides they like you? Friend dates and hangouts eventually, then maybe more?

I realize that everyone may have a different interpretation, but if you're a guy and you say this, I'd like to hear your thoughts.
