Stinking is party of backcountry hunting. After the first 3-4 days when you start get nice and crusty. Work, text messaging, social media etc all start to fade from your daily habits and you begin to focus on nothing but hunting. This is when you really begin to get into the mode of backcountry hunting. If you were a pro athlete, you might show up to the game day arena in a suit and tie, but once you put on that uniform and start breaking a sweat during warm ups is when you start getting into gear and get focused. If you were to go to the locker room during half time, take a shower and put on some clean, fresh clothes, you would totally derail that mindset.
You'll feel your dirtiest on day 2 or 3, but by day 5, you'll totally be in the zone. Just go with it. Embrace it. If you can't go a week without a shower and clean clothes, stick to the front country.
