my boyfriend's armpits

Varuek

Doliphor

Poudrextase

Escentric Molecules Molecule 01 – A minimalist skin scent with a warm, woody, “your skin but better” effect.

Juliette Has a Gun Not a Perfume – Clean, musky, soft, and close to the skin.

Narciso Rodriguez For Him Bleu Noir – A masculine musk with a fresh, intimate feel.

Flora Gorgeous Gardenia Eau de Parfum is a feminine scent, but it's completely 100% armpit to me. I could be weird for that, though.

Nasomatto, Francesca Bianchi, and Marlou certainly have several armpit scents between them.

Annapurna Wren Atelier It has a Biryani and Sour milk in it. This personally really reminds me of a smelly armpit.

I would like to add something about the often suggested cumin as a note: Some people perceive this as sweaty/BO indeed, but others perceive it as soapy (funny enough ) This goes for tasting cumin as well as for smelling it, so one should always test first. 

I certainly never perceive it as soapy. I even smell my own armpit and everyone elses with that note haha. Also it makes sense, the stuff you eat can certainly create a certain odor.

I've read it depends on ones genes which smell (or taste) one gets from cumin...Strange isn't it?
