Smell down there dependingo what I eat ?

As the title says I’ve noticed a change in smell down there after eating certain foods and not sure if anyone else had experience this or if it’s normal? At first I thought I had something wrong because it smelt like fish but I started realizing is smelt like fish when I would eat sushi (crab/shrimp) then the same thing with burgers and know with fried chicken after eating chicken express( I noticed when I peed ) is this normal ? Has anyone else experience this ? Can I fix it ?
