To be honest your webbing is quite minor, so much so that I personally wouldn't consider surgery based on the images alone - but of course not experiencing it first-hand, I can't say how much of its impact warrants some kind of medical intervention.
You don't gain any new length through this method, but for some guys they find they get to maximize the length they were born with because the skin flap (webbing) is less of a discomfort or impediment when having sex.
Scars I've seen in the past weren't large and generally well concealed by even a small layer of pubic hair. Also, these scars would typically reside under the shaft at the base where it's not plainly obvious unless unless examined.
I would check with
Androfill, they have a network of Doctors and I would be surprised if they couldn't provide you a strong recommendation, but again, I'm not so sure your case is a significant one (that'll be up to you and your Doctor to decide).
