Avoid perfumed soaps, feminine deodorant sprays and cleansers, and tampons and pads with deodorant. Do not douche. Douching can wash away the healthy bacteria lining the vagina, as well as alter the vagina's natural pH level. Use only plain white unscented toilet paper. Wear underwear, tights, and pantyhose with cotton crotches.
Tight clothing creates warmth and moisture which are favorable for the growth of yeast or bacteria.
Wipe yourself after urinating from front to back so that bacteria from your anus will not get into your vaginal area. Wash your sex toys with mild soap and warm water. Use a condom on your sex toy or boy toy during intercourse. Change the condom between anal and vaginal penetration, and when sharing sex toys. Use a lube for sex.
