after i had sex over a week ago my panties have had this white stuff in them, and i've seen it before but i never thought of it being anything, but then it started itching. it's not all the time. but sometimes it does itch. at least 3 times a day i want to scratch it. it doesn't hurt and it doesn't burn. so i don't think i hav a yeast infection. wat is wrong wit me?? plz help.
