Why does my boyfriend's *** taste different?

I recently decided that I was going to try my boyfriend's *** so see how it tasted. I have never tried *** before but I heard it was very salty and/or sweet depending on what he ate. I looked through many answer from people but none of them matched up to what my boyfriend's *** tasted like. I can't really describe it because it was kind of tasteless. It was just plain dull. Should I be worried?
