well stop stuffing your turkey sandwiches in her *lix*

So what happened later?

Sure. Be truthfull. Simply tell her the taste is not to your liking and she'll either accept it or won't. It may be a good chance to try other options however, like having her use a flavored douche or trying a bit of cherry juice or whipped cream. You might find that if all that stands between your dislike of the taste and her satisfaction is a little flavoring. It can't hurt to try anyway. If the problem is other than taste, you'll have to try other ways around the issue.
