I've also heard that Cinnamon can improve the taste and that in general, avoiding foods with rich spicy flavours and chilli can help, but who on earth wants to do that?!

I think KateKate42 is right about it being an acquired taste and I'd say the best way for her to acquire it is to make sure she doesn't feel pressured to have it in her mouth if she doesn't want it. And also, show her that you don't find it distasteful either. If she has taken it in her mouth, don't shy away from kissing her afterwards otherwise you're sending her a message which says you want her to do something you wouldn't do yourself. That's not what sex is about and it'll put her off even more, I'd have thought.

Just remember that it won't happen overnight. Give her time and I'm sure she'll learn to love it. After all, who liked alcohol the first time they tasted it?
