So my boyfriend just sucked my nipples and after about seven minutes of very rough continuous sucking he started smacking his lips and I asked what was wrong. He said that they tasted funky so we stopped. A few minutes later I started looking it up thinking it was breast milk and found other women talking about a metallic taste but I couldn't find a straight answer for the cause or what to do about it. I licked mine to see if it had that taste and it did, and my boyfriend said it was a kinda metally taste. This is the first time that he's ever sucked on them that rough for that long, and he says that he likes the taste but I still think it would be weird for him to taste that while he was sucking. Does anyone know the cause of this or how to make it go away? (It's not
pregnancy. We aren't having sex, just intense foreplay.)
