What's your vagina taste like?

So this is embarrassing but I'm not sure what your vagina is supposed to taste like. I have normal clear and white discharge. I get regular paps. I wash my vulva in the shower but I'm always so worried what my boyfriend thinks when he goes down on me or when he's rubbing my clit but then will lick his fingers to get me more wet in the beginning. Obviously I don't sit there and taste my vagina 😂 but there's been times where I'm masterbating myself and use my spit to lubercate it more and it tastes sour. I don't know how to fix it?! Everything is normal and good down there. I've never had any problems down there. I keep it clean, I just don't know. Is this normal? I'm just so worried my bf will think it's nasty! But I really do take care of my lady bits!
