Is the 60-40 thing true?

hello16
Like in the movie HItch, it was said "you go sixty and let her come the rest" on a kiss.

So is that true?

If so or if not then how do you go about it? I feel like it may be a bit awkward for the guy going in if he has to wait if she's wondering what he is doing..

The real question I suppose is how do you go about kissing someone for the first time?

Any and all help welcome. to critics.. you don't know my previous sitiations, so please don't assume and comment. As the saying goes "If you assume you make an a** out of you and me."
