Excess sweating!!

Ok so does anyone else have this problem? I work at a department store and I do alot of walking around. And it's not even hot in the store but at the end of the day, my underarms are sweaty, my cheeks are always a little sweaty. And... tmi but my lady parts even swea!! Is this normal? Does anyone know how to calm the sweating?!?! It makes me so self concious.
