Is This Normal for my Belly on?

Use a q-tip to clean it. I have to do this to my sons. I think the security monitor they put on them in the hospital made their belly ons form funny. (that thing was heavy!) Also, you may have gotten something "in" your navel. I am a hairstylist and sometimes get hair splinters in mine...it's actually quite painful. But anything in your skin, if left untreated, will eventually cause an odor. Sometimes just not DRYING your belly on well will cause the problem you are having.
