Do you really think that different races have certain pheromones?

At first I didn't but now I can smell it...I won't smell it from my own race but I can smell on different races...I know it could be a popular food choice within that race, because at the end of the day we're all humans but it's like I can totally smell it...anyone else have this experience? All answers are accepted..I don't report and I'd appreciate if no one else did, so if you are...just don't answer the question
