Hair on the torso can be a problem, and when you’ve got a ton of it, it’s just not attractive. You’ve got to help nature out a bit and redesign it the way nature could have done it. Chest hair or torso hair works when it’s not too long and also doesn’t look like you trim it.
How long should chest hair be? That’s the tricky part, but usually 1/2 to 3/4 inch long looks natural.
The best way to trim chest hair is by using clippers with either an adjustable guard or a set of different removable guards. On the chest, hair can all pretty much be one length. On the abdomen, you’ve got to navigate around the line of hair beneath the belly button. Women find the “treasure trail” there sexy, so you want to keep it longer -- maybe by not trimming it at all and just clipper-ing around it.
If you’re just cleaning up the non-chest areas and don’t have much hair on your abdomen anyway, shaving works. Just leave the treasure trail alone.
