I'm 16 and I have been shaving my pubic area for a couple of years, I know how to do it, what it's like etc, and I have searched the internet but can't find an answer to this - when I shave, it goes smooth, but then I have to leave it at least a week before shaving again, if I do it before that, it hurts a little and it does not go smooth. I have heard my friends say they can't go a few days without shaving, why does it not hurt them and why does it not go smooth for me unless I leave it a week after the last time I did it?
