Oral despite the crap coming out of you

I've noticed a lot of white discharge come out my vagina during different times of my cycle. This always makes me feel yucky and I never feel comfortable getting head because of it. Also, I always find this white discharge on my underwear and I hate that, because I feel concerned that someone will think it is disgusting. Do you guys feel the same?

Also, do you guys wear panty liners because of this?
