thick thighs & chafing

hello all. so it's finally warm out there (I live in Wisconsin we just got warm weather last week). I was just wondering what you all do to protect against chafing in the creases of you pubic area. and what you do to relieve it?. so I'm going to give a bit of TMI here but I am done of these women who are always moist down there... have always been. so sometime in the humid months the crease where my leg and pubic area are will get chafed. my underwear will rub against it and I have to change styles or go with out and I just recently got this app so I wondered who else has this issue and what you do about it.
