Pineapple juice definitely works. So does kiwi. Dunno about other fruits.

Sadly enough, I haven't gone down on him since I posted and got all the great advice, nor have we tried any other foods/juices.

Seababy, thanks for the analysis! I'm going to try with the positive affirmations and self-talk, and the swallow-all-at-once technique. Regarding the mental aspect, I've also found that I'm more willing after a few drinks, but I don't want to make that a habit. But sometimes I think if I could do it a couple times with some little handicap like that, it might get me over it.

Anyway, here's the recipe for tasty fluids, for guys and girls:

three days in a row

1 cup pineapple: fresh, canned, or juice
1 cup mango juice
1 banana
half cucumber, peeled and seeded
half teaspoon fresh ginger
half teaspoon vanilla extract
two tablespoons honey
