I'm not sure if this is something to worry about. I have always had this.
But I think my meatus looks different than on pictures which I have seen. On the left side of the slit the labia or whatever you call this looks different than on the right side and it almost looks as if the mucous membrane which is in the urethra actually goes outside, as if the material which this stuff is made of is the same material the mucous membrane in the urethra is made of. Sometimes this tip also gets red and then it has exactly the same color as the mucous membrane in the urethra.
Is this normal? I made some pics.
