Your guy's grooming is a big deal these days, according to men's magazines and style guides. Manscaping – or trimming all that excess hair from various parts of the body – is definitely a trend. Before you tie him down and force him to shave down some of that manly fur, consider his feelings about it. If he's game to trim those tresses, then it's OK to help him out. If he wants to make a change in his hairy landscape, then grabbing a razor and some shaving cream definitely isn't the way to go about it. A few rules of thumb according to AskMen.com are as follows. First, there are very few areas of his body that need to be super smooth -- like your freshly shaved legs -- unless he makes a living as a stripper, AskMen helpfully points out. Nor should there be wide swaths of hair the length of a five o'clock shadow. Stubbly chest? No, thanks. The best tool for a natural look is a beard-type trimmer with several guards to ensure the right length.
