Yes, I smell the same odd smells unexpectedly too. Especially on my hands - a strong metallic, sour smell. I've asked my ex & my current spouse to smell my hands & they said they didn't smell anything weird & that it's just in my mind. I also get disgusted by eating noises - I can't be around anyone that is making them nor can I stand to listen to myself. I will actually swallow a particularily noisy bite whole to avoid the disgusting noises. This drives my husband nuts! I'm not sure why this bothers me. I could be wrong but, I think I'm associating eating noises with sexual ones & it totally grosses me out! Maybe the weird smell is the same thing too? It's strange but, I guess I'm with you too!
