Mine was getting a bit too 'bushy', so I decided to shave it.
It was SO itchy growing back - so I told myself that would be the LAST time I shaved.

But since then Ive done it two or three times, and once your used to it it begins to itch less.
The only problem is keeping the stubble away

My girlfriend prefers it like that, and thats why I have it shaved right now.
But I guess it just depends what your partner wants, really..
