I grew up with 3 brothers and I never lived with any boyfriends before H.
So when that musty "teenage" odor started to appear strongly in our bedroom as soon as we moved from our house to the apartment a few years ago, I just thought, "Oh, that's how men smell" and I also figured I was noticing it more for some reason because we had just moved to a new place and maybe it was just more noticeable there.
I just explained it away. But H had been going to the gym every day for years and it wasn't until then, when I figure his MLC was starting, that I really noticed the smell. It's like his sweat smelled different...stronger.
I agree, it seems very likely it could be due to hormonal changes.
He had also secretly started drinking then. I don't know exactly how much alcohol affects body odor, but I do remember reading somewhere that it does have some effect, something about how the alcohol breaks down and comes out your pores.
