Hmmm I smelled of onions before transitioning but my hormones were out of wack before that. I'll ask one of my friends that was a body builder before her transition if she noticed a change.
It was such an eye opener, I was 29 when I started talking to a therapist about it. Once I let go of the fear it was waves of realization that things started making sense.
I think it's diet dependant. I notice there's a distinct change in my body odor when my diet contains a great deal of onions and spices and a general acrid scent that's somewhat evocative of funky cheese.
I have two perspectives to this. I once had several male Indian roommates and I honestly don't remember them having a scent beyond "male". I could pick up turmeric from one of them, but I think he used a turmeric toothpaste.
I'm white and afab (not on t at the time) and a decade after having those roomies, I had a half-Indian friend tell me I smell like her dad lol. I think curry odor might just stick to clothing, I make it a few times a week so I'm sure my whole house smells like curry to outsiders at this point
It reminds me of how there is a gene that determines whether eating asparagus makes your pee stink, and there's a different gene that determines whether you can smell it. I had a friend who didn't have the stinky pee gene, but her boyfriend did, and she complained of the smell when she used the bathroom after him occasionally. He had the stinky pee gene, but not the gene to be able to smell the stink.
This came up in a random conversation with my friend, before she knew about the genes thing. I was so excited that I got to tell her about a cool science thing that I couldn't speak for a few moments.
