I have been having a white discharge for a while now, and it is kinda smelly but not too bad, its not lumpy so it's not a yeast infection. Every time I pull down my underwear, there is this white discharge in my underwear. I have been having sex for 3 years now with multiple partners. I have heard its normal or can be an STD. I am kind of freaking out. I have no other symptoms. I was wondering what it could possibly be? Should I be worried? How can i get rid of this discharge?
