Do guys notice or care about..?

girls sweating like their underams... my arm pits sweat a LOT when im nervous or just hanging out with people and i get really insecure about it.. this guy i like (that likes me) has been hangin with me lately and i just feell soo insecure about it with him cuz i dont want him to like smell it or anything and be weirded out..soo i always kinda act kinda weird cuz i dont want him to notice it...he always hugs me when he leaves too and im terrified that im gonna smell bad every timee.. i wear perfume..but i dont know how much that helps.. (i put on deodorant too but it like wears off) should i really be worrying about it?
