I'm wondering if you're smelling your own sexual desire.
I know pheromones are odorless but there's something releasing.
Quoting LittleTiger:" Its possible. Kind of like when other women know a woman in a bathroom is on her period. You can just tell..."
I can only tell when I hear the crumpling of wrappers, lol.

Sometimes I can tell the difference in the odors in the room. Smells like death. haha!
I was watching a show a couple years back about women being able to tell when others are in heat as well. Plus you also sync up with other women that you are close with. So strange but interesting! My mom and my aunt sync up to me. They always know when I have my period because they dont feel well.
