Um... Nipples?

I’ve noticed whenever a partner sucks on my nipples, their breath stinks immediately after. Like, I don’t even want to kiss them anymore. It’s like the same sharp, almost metallic, smell no matter who I’m with (i.e., it’s not their breath).

I used to be obsessively clean: scalding showers twice a day, scented body washes, etc.

Now, I’m a little less neurotic: daily warm showers, unscented, “organic”(🙄) toiletries, unscented “green” laundry detergent, etc.

Nothing I do seems to matter -except- every now and then, I’ll notice a little white film in the crevice of my left nipple. If I use my pinky nail to get it out, the breath isn’t as bad.

I have no idea what it is, or if it’s normal. But it’s been literal years.

I asked my gynecologist about it once, but tbh she terrifies me, and she just sort of brushed off my worry. (Yeah, I’m looking for a new one).

She said it was my then-boyfriend’s breath. But it’s been every single person I’ve been with (if I forget about the left nipple).

Someone. Please tell me I’m not a mutant, and this is my weirdly backfiring superpower.

Help.
