No two "servings" (if that's the word to use) tastes the same either from the same man or a different one. From my experience (pretty extensive) there is always a salty flavour somewhere in there, more strong sometimes and less on others. Also the viscosity can be infinitely different varying from almost 'jelly like' to just pure liquid.
Most definitely, it has never tasted the same even with the same guy. It is has to be in the diet.
It depends on the diet.. I read somewhere that Milk makes his spunk funky and citrus and fruits make it better...
For me, I have never tested these theories, but even the same man will taste different from time to time..

I have only one word to say about how to get delicious sweet cum...PINEAPPLE! (seriously, and that goes for both men and women)
I know I have answered this before but in any case of course it does taste different every time. As so many have said diet plays a big part in the taste.
