I have been seeing a woman that, when ever I kiss her, some time later my lips tingle, "no" it is not because it was so good" lol, but like you used one of those lip balms that have a little spice to them. Any ideas would be appreciated.
I've been have similar problem and not been getting any answers from dr's I,ve asked my dentist, doctor, dermatologist and ENT specialist. They all said the same thing "I don't see anything".
Recently started seeing a new girl and shortly after we started seeing each other she started having problems with her lips.
We are both smokers and wonder if we're having a reaction to the new chemicals they have added to make cigarettes fire safe. Because my issues started about the same time they started adding that stuff but it's weird hers didn't start until she started kissing me.
she may be using a lip enhancer, aka a plumper. how it works: rub on, irritates lips, lips swell up.
next time, check to see if your lips are any more swollen than normal... then that's the case
