I have clammy hands....do guys care?

are there any treatments to excessive body sweat? I get on mostly underarms and hands for sure. I am 14 female...is there anyway to grow out of it? It's frustrating and even when I have my hands on my jean legs for like three minutes they are cold because my hands are moist. And sometimes I'll just be sitting in my car and it's normal temperature and I can feel sweat roll down my arm. it is THE worst
