Thick/rough, scar-like skin.

Hey everybody, I'd like to start by telling you guys that I've just recently discovered this subreddit and that I am amazed by the positivity and by how well-developed the different approaches are, you guys are amazing!

Now, I've decided to give it a try and have been tugging with manual method 2 for a little more than a month now, and I've realised something: My skin around the shaft started feeling pretty rough and thick, almost like scar tissue. Naturally, this has me a little concerned, so I wondered whether anyone else had ever encountered a similar problem? Any advice is welcome.

Cheers and KOT!
