Today is the first time I've looked for an answer and your right, nobody has a serious answer. I haven't breastfed in six years but I thought that was it. But I also have implants so maybe that? I would bet its hormonal but I'm really hoping someone can post something that would make it better. If it makes you feel any better, you are not alone and I was so upset when someone told me they tasted funny. Doesn't sound sexy to me. I blamed it on the milk.
I first experienced this with my husband, the weird onion type taste, then a lover. I thought it was just because that was how they were built, nothing more. However it recently happened to me, where I was the one with the weird tasting nipples. I am a very hygienic person so it really freaked me out and has made me terribly insecure. I don't have implants so I know it's not that. I tried to think of what the three of us (my husband, my lover and myself) have in common; we all drink A LOT of coffee. I am wondering if that is the culprit? That and I've noticed as of late, I've not been drinking enough water. I don't know if that is what the cause is but I though it worth mentioning.
Try soaking a cotton ball in lemon juice and rub it on your nipples once a week. Works for underarm odor as well. Works for me...... Good luck and hope this helps.....
Onions, like garlic and chives have Sulfur compounds in them. It's what gives them their taste.
Sulfur is the 3rd most abundant in the body and 6th most in breast glands.
You are tasting keratin. It is a sebaceous fluid contained in the Montgomery glands of the areola. This substance works as a lubricant during breastfeeding. That would be its primary purpose in nature. Its secondary purpose would be to keep Daddy from stealing all of Mama's milk from the baby. It doesn't sound like it's working given the amount of persons on the internet seeking to have that question answered.
Still no answer, to all it's 2018 and my wife hasn't been pregnant, still she tastes like onions
Been looking for answers to this as well! My boyfriend recently told me my breasts always has a taste to them but I don’t know what to tell him that causes them to have an onion like taste. Even after I get out the shower and we get intimate I can taste and smell his mouth like onions. All I can think is maybe the soap I’m using? Maybe I should be using an unscented one instead of a strong scented one..
To anyone still questioning the strange nipple taste. First off, ladies... It's not just your nipples! Go ahead, give your man's nip a little tounge action, you'll get that same taste.
The issue isn't the nipple alone, that's only a contributing factor, the real culprit however, is natural bacteria in your mouth, mixing with keratin, which is naturally produced by our nips! (Yes, even males) a quick cure to this... Try brushing your teeth before any nipple play, the recent brush will eliminate the bacteria in your mouth, thus... Making the taste vanish! Have fun! #nippleplayforlife
Cancer? I have had this "nacho/Doritos" smell from the time I found out I enjoyed nipple play to age 43, both before and after having children and breastfeeding so that didn't have any bearing on it. I smelled it on my partner's breath and in the air. It was very strong. I've also had very strong BO, with a similar onion smell and used prescription strength deodorant constantly. At age 43, I was diagnosed with Lobular Breast Cancer. It is breast cancer of the milk-producing lobes, not the milk ducts which is more common. I had a mastectomy of that breast and not the other which was clear. Since then, the remaining breast has had no odor whatsoever, and my BO is completely gone, despite switching to weak all-natural deodorant. In my personal experience, it seems like cancer might have be the cause. Lobular breast cancer is invisible on mammograms. The cancer was extensive in that breast and there was no saving it. It was 5mm from my chest wall, 5mm from my lymph, and all the way to the nipple. It was there growing for many years and there was no way to detect it until it became so extensive, my nipple turned just slightly. I just find it interesting that the smell from my nipples and my armpits went away once the cancerous breast was removed. My remaining breast and nipple get twice the attention now, and there is never any smell whatsoever. I'm even wondering if both didn't smell before, and I just never realized it because both always got attention.
