15 years ago post op. I hadn't dilated for years, and was concerned about depth/width so I did it again the other day. I was amazed I had apparently not lost any depth or width! Not something I recommend though. Remember, skin can be made to stretch longer & deeper if you take it slowly, don't push or tear anything. My partner on the other hand has nearly completely atrophied from never dilating, so I think its all personnel. It was her choice not to.
