Do men ever daydream about girls they barely know?

Us girls often daydream about guys we just started dating/taking to. We plan our next few dates (or even relationship) before we even know the guy well, and this causes us to get attached more than the guy. I am not speaking for all women, but I know a lot of them who do this, myself included. That’s why we often like a guy too much after only a few dates. Do guys do the same??
