Weird, but it is not the first time I’ve heard this concern.
Too wet? To me, that is like being too happy or too sexy. Any guy that thinks you are ‘too wet’ has some bigger issues lurking around the corner, most likely. I don’t even know how you would criticize a woman about anything, even something legitimate, in her intimate times. But being too wet is total BS.
So no, it’s not bad that you are ‘too wet’. If he has an issue with it, he should get down there and lick it up. That would be my approach.
