I've always had this as well, and I'm relatively loosely circumcised. It's most pronounced when I'm fully erect and my scrotum is so loose that my balls are hanging very low. Don't have any good pictures of that as I find the look less than esthetically appealing. But even when my balls are sucked up tight (as in the attached) the webbing is evident. It's never been a problem for me or any of my partners and only one person has mentioned it to me.
