how do I make myself taste better

So I have always wanted to be eaten out, like, that's what I think to be the most amazing feeling is being eaten out, but my boyfriend really doesn't like doing it because of how I taste... he's tried before, and did it for a little bit and it felt amazing, but he couldn't continue after about 2 min because I tasted so bad to him, I've heard about drinking cranberry juice, does that work? And what else can I try??? Please help me...
