White milky discharge <l>?

any1 know what this could b? for a long time now i've noticed this and i thought it was ok but it actually grosses me out when i have or insert a vibrator/ after awhile it gets filmy i've also noticed sometimes if i use my finger it feels thick it doesnt really have an odor i guess it sort of does sometimes...like ew this is beyond sick but mashed potatoes???? and i've also noticed this on my undies sometimes. i can't figure it out what is going on? is there any way to get rid of it? and to clear a question nope no itchyness and it doesnt happen after or before my period its everyday
