Discharge and receiving head

So this is sooo.. embarrassing but I get sooo much discharge it makes no sense. Like I used to wear panty liners all the time to keep it off my underwear but the doctor said that it’s not good to wear them everyday so now I don’t, but I have the urge to change them at least twice a day sometimes. Now I have a boyfriend and he wants to go down on me but I’m so scared that it’ll be a whole mess and that he’ll get freaked out or something. Has anyone ever experienced this problem??
