What Is Causing My Skin To Peel?

Hi there, i have had some kind of a break out i guess. I have had my skin pealing off on my bikini line for the past few days. the first one showed up after a day out at the beach and i though that it was just a rub from my bathing suit bottom. and then a few more showed up this week what can cause my skin to peal like that it doesnt hurt or itch its just weird
