text: whenver it's my period time i exprience stange rashes in private part what can use to cure this or whats cause   ok first of all it doesn't mean you have a std of any kind. sometimes women, more in overweight women get a rash in the folds at the legs, the side of their twat. this can be cleared up with zinc oxide or the over the counter stuff for yeast, like the stuff you use on your feet.
