How we keep Noisebridge safe

So I just turned 18 last year in November and I have been experiencing a crazy boob growth spurt. I was always "average" chested in middle and high school. I was about a B cup in 8th grade and grew to a C cup by my freshman year. I remained a C all through out high school and I thought that was it for my boobs growing. Boy was I wrong. The summer after I graduated high school is when it all started. I was 17 and I would notice change in size about every month. By the end of that summer I got measured and I was a DD. I kept growing and growing. I was a DDD on my birthday. It was exciting finally having boobs but also scary. My boobs didn't(and still haven't) stopped growing. I also have gained some weight since I don't do high school sports anymore. So with that and the growth spurt, right now I am currently a G/H cup. They're huge!! So anyway, that's what I meant by "New boob". Now, to the "problem". So I love sports bras. It's pretty much all I wear. So one Saturday, I stayed in all day with my roomate. The apartment was pretty messy so we decided to clean up all day. The air conditioning was not working in the building so we had the windows open.( didn't really help much considering we live in the South) I had on a tighter black nike sports bra that day. We worked all day in that warm apartment. When we were done around 5pm, my roommate and I kicked back on the couch to finally rest and watch TV. I started to smell something strange. I couldn't quite make out the smell. I kept catching brief whiffs of it. I smelled my armpits and they smelled like my deodorant. So what was giving off that smell?? I started to notice the smell was stronger when I dropped my head and was closer to my cleavage. I then brought my boobs closer to my face (yes, they're that big -__-) and that's where it was coming from. The smell was a kind of musky/musty scent. Kind of vinegary. Like the smell you get between your toes when your feet are real stinky, but not as strong. It wasn't offensive like B.O. It smelled different. I had never smelled a smell like that on my body before. I even rubbed my fingers deep in my cleavage and under my boobs and played the "smell my finger" prank on my roommate(we play around like that. We're close). She remarked how it smelled like vinegar. It went away after I showered. I figured the smell resulted from the sports bra suffocating my boobs all day in my hot/humid apartment. It's a little embarrassing to talk about so I came to this subreddit of course. I figured one or two people here might experience this. Is this something that usually happens to women with big boobs? How often does this happen to you guys? It's happened to me a few times.
