Is it my heightened sense of smell, or do I stink?

Duuuuuude. I'm having major smell issues. As in, I stink! All I can smell is my own BO. I'm sweating like crazy and I feel like I totally wreak. Yesterday in the shower, I washed my armpits 4 times. I sniffed them after each wash and they STILL smelled. I was SO embarrassed in class last night, because I was sure everyone in the room could smell me. When I got home, I made BD sniff me, and he insisted that I was only a little bit stinky, and that he didn't notice it until he stuck his face in my armpit. I guess that's good, but it doesn't change the fact that I am driving myself nuts with the way I smell. Yuck.
