For the last week I have noticed my nipples are a bit dry and flaky. Nothing severe, but I have never experienced this before. I have no other symptoms and actually had a breast exam less than a month ago during my annual pap. And no I am not pregnant. I have been taking b/c pill for a year now and just finished my period.

What could it be? I have a feeling it might be the recent cold weather, coupled with my boyfriend touching/playing with them during sex. They don't hurt, but I wonder what it could be. Thanks!
