There is not a wide variety in the flavor of precum. Mostly it's nearly flavorless and sometimes a little salty.

You have to suck a man to climax and take his load of sperm to get his full flavor. As a gay man who has taken eight or ten thousand loads of sperm from two or three thousand different men, I can assure you that there is quite a variety of flavors. Sperm is mostly salty and a little bitter, but it can range from almost flavorless to slightly salty to moderately salty to very salty and from slightly bitter to moderately bitter. Different men have different flavors and even the same man can have different flavors depending on what he has eaten recently and other factors.

After a man has given me his sperm I like to hold it in my mouth and swirl it about to get the man's full flavor like a connoisseur savoring the flavor of a fine wine. Indeed, one might say I'm a sperm connoisseur. Sperm is wonderful, it's the nectar of passion.
