How come my breasts sometimes smell similar to sweet breast milk?

I'm 17, I've never had sex and I'm also not have a child. Sometimes in space heater weather usually, my breast have this aroma, it smells merely like breast milk, I know from when my sister have her 1st child. But, why? I mean, it doesn't smell horrid or anything, I infer it might attract actually, but why? Also, I wear a 38C bra and sometimes I sweat as ably under my breasts, do you believe a push up might help that problem? I really don't want to wear a push up, these jug are big enough already. Thanks!

I can't propose any advice on the subject of the scent, but I've got a big chest too and sometimes tot power helps on those hot summer days. : )

Wut is resembling the best condoms?

it is probably the sweat you're smelling. There's a product by Monistat called "Soothing Care" that relieves & prevents chafing. You can use it underneath your breasts, inner thigh & bikini area to control sweat from moisture, bake, movement & shaving. I also sometimes just use deoderant underneath my breasts. Of course I use a separate deoderant for that area and for my underarms.
