DEPENDS......WUT THE FUCK ARE SWEAT MARKS??....TELL ME AND ILL TELL U IF ITS NORMAL OR NOT

ok, you need ANTI-PERSPIRANT deodorant, the white stuff, get speed stick because yellow sweat stains on your shirts is really gross.
thanks.

Every now and a gain wash your underarms with shampoo this removes all traces of old deodarant build up. Try a good quality deodarant too.

NO! nooooo!! you are a freak for all this sweating you do! get some spackle or spray sealant, seal up them pits and take care of those SWEAT MARKS NOW! also, you should definitly not be on this site if you are thirteen...don't you have homework to do?

OOOOOOOOOH NOW I GET IT....ITS NORMAL...JUST LISTEN TO THE OTHER COMMENTS

I THOUGHT U MEANT "SWEET" MARKS UNDER UR ARM PITS I WAS LIKE WUUUUT?

You can't be as dumb as your question. Do you know how to walk or do you still crawl? If you don't sweat under your arms see a doctor.
