help/advice anybody?

wouldn't usually post things like this, but, for the last few week around my nipple, there's been really dry flaky skin and it's been itchy and sore, and I'm not really sure what to do? I've tried creams and things for dry skin, but nothing has worked. I only live with my dad and brother too and is feel really awkward asking about it, even though we're really open about things like this.
