"Can you use a Fisherman's Friend when performing oral sex on a girl?"
Can you use ‘Fisherman’s Friends’ when you go down on a girl? Is it harmful?
Yes - she’s likely to kick you in the face for trying it! I’m guessing you’re getting the idea for this from the mint-in-your-mouth oral sex trick. Sometimes, sucking on a mint before giving someone oral can feel quite tingly. Same goes for sucking on ice or even taking a sip of hot coffee first. Some people like the feeling, others don’t.
But Fisherman’s Friends are VERY strong and I honestly don’t think the feeling would be pleasant. Also, the pH balance of the vagina is very delicate. Lots of things upset it, causing yeast infections like thrush. I honestly can’t say for sure this would cause it, though I will go out on a limb and say I don’t think it’s going to be up there on the Top 10 Things I Love about My Boyfriend list.
