I only ask because this is happening to me I've googled and women say they have a problem too. after my SO sucks on my nipples he says it tastes like onion,garlic even rusty like taste. I cut onion and garlic out of my diet and get the same result. I bought all new bras same result. I changed body wash same result. I guess Im asking for any advise and other women who may have this issue.

ps. He isnt the first man to say this. Ive dealt with this my whole sex life.
