Odor advice

Hi! Since I started using marijuana, I noticed something: when I sweated, a strong smell invaded my body and armpits; a strong marijuana smell filled my nose. It felt very strange. At one point I thought it might be a problem with my hygiene, however, despite all my attempts to get rid of that smell I haven't been able to avoid it. Does anyone else have this problem? How can I get rid of this smell? Is it normal? Please help!
