changes , should I be worried

so me an my boyfriend have been having sex for awhile and like before I wouldn't get the white mucusy stuff at all and now it's like a waterfall lol and I don't like having sex when I have that cause I think it's just embarrassing , like before we would be fine and I wouldn't have that but now I do and it doesn't go away either should I be worried ? or is it normal ? does that interfere with sperm to get to the egg or not ? Help ? Anyone ?
