yes there are but if many different ppl have told you you smell you do. I went to the first gyno I visited and told him about my struggle with the odor and things I've tried and he said "i dont smell anything coming from you, they are just jealous" HA I WISH. If you've heard it numerous times from numerous ppl it's true. I've also been told by doctors im bulshitting about medical problems i do in fact have because it didnt show up on certain tests but its there along with this odor! If you honestly dont smell and you think you do, you might have a somatic delusion or delusion (beliefs not based in reality) but do the test I've mentioned previously. Some ppl do believe they smell or have body dysmophic disorder or some things like that but you will know if you smell it will be an objective and subjective experience, ask other people not just your friends but other coworkers but yeah if you've heard it from real ppl on numerous occassions then you might have a smell.
