I'm a new DE user and All the reading says not to press the razor into your skin . . rather to let the razor's natural weight do all the pressing. My new DE is 60 grams, which feels pretty heavy to me after using nothing but plastic disposables. So I just want to make sure I'm doing it correctly when I just let the natural weight of the razor lean in against my skin. Is that right? Are there times when you lift up a little and lighten the load in sensitive areas?
