Tessie is quite right about that happygirle. If you are right out of the shower you will taste about the same as if he licked the back of his hand. The taste of your lovers sex is an acquired appetite and will in time come to be seen as a relish from the condiment table of lifes erotic feast.

When as a child you take your first taste of beer it may be revolting to your palate and leaving you wanting to spit it out.
With time and the advance of adulthood, however, you may
take sips of beer and learn to tolerate it. Later you may learn to enjoy this beverage and thirst for it. You probably can list things you enjoy today that you wouldn't have as a child.

Some time ago there was a cinnamon flavored oil which felt warm when applied. It was made by Kama Sutra. They made whole collections of oils, powders, and balms.

Some enjoy the flavor and lubrication of natural coconut oil. I would suggest buying it from an adult supply house as it will be processed for the purpose of sex, thus being safe.

I've seen mint flavored condoms for the girls who have a problem giving him oral and live in fear of getting a mouthfull of his cum. There was a company making these latex sheets
which were about six inches square for placing over a womans sex like a little condom blanket. She could hold it in place with her fingers while her lover could place his lips and tongue to it to give her pleasure.

You could even use a sandwich bag from your brown bagged lunch at school like the kids are doing now. Just a thought.

You can use a little chocolate sauce or whipped cream which is yummy.  

Although I will add that just because he doesn't care for the taste is not an excuse not to get used to it and learn to like it. Have you tried having him go down on you when you are straight out of the shower. The cleaner you are the better he might like it. Maybe use some nice sort of lotion on your stomach and legs too. Smell and taste go hand in hand.
