Really strange, almost repulsive give somebody the third degree.?

My boyfriend won't perform oral sex on me because my fluids are too strong. He say in small amounts I'm the best hes ever taste. But when I get really excited I engender a lot of stuff and next it will taste "bad". Does anyone hold any suggestions of what to do? Or why this is happening? He can other have a tacky wash cloth at appendage and gently, even sensually wipe sour excess "stuff". It may be that it doesn't taste unpromising, it just overwhelms him.
peace
check your food.( we enjoy the same situation ..and i love it, i'm the man)
