Chub rub?

Molly
Ok so as my belly continues to get bigger, so does everything else it seems.. (Arms, boobs, butt, legs, etc) I'm not a big girl to begin with so I was completely unfamiliar with chub rub until now 😩 I live in sw Florida and the heats been bad lately and my thighs hurt when they rub together. Does anyone know of anything to help the pain/irritation?
