I've always been told when your boobs itch, it means they're growing! haha...don't know if it's true or not
normally if u have been exposed to the sun or tanning beds you could be itching .. i get that alot when i tan
or maybe a particular soap or lotion u started using could just be reacting to a sensitive part on ur chest.. or have u began a new product for chest acne?
just ask yourself if u have used any new products.. thats normalyl what it is
dry skin, your bra's fabric irritates your skin, or the possibly something in the laundry soap.
Hmmm. Either per- menstrual, or you need to get to a chemist for a pregnancy test
maybe i have sperm that makes you itch because after u and me did it i got a call from a girl that said the inside of her vagina hurt
