Facial hair is men's alternative to wearing makeup.
I've not been legitimately clean shaven with a proper razer blade in probably 4 or 5 years, I've a trimmer that goes from 0.4mm - 10mm & what length it is depends on the mood really. I'll occasionally whip the head off it completely & use the trimmers blade, it's a close shave but not razer blade close & leaves me with some shadow.
I think the only men who should be clean shaven, are those that have problems growing facial hair ie overly thin or patchy.
