[PENub]

Hey everyone, I'm new to this forum. My names Chris and I'm in college right now. I'm about 5.8'' but 6'1''.. just a little information why i want to PE.
Actually I think this is the first time i've ever posted on an online forum, but this place is really interesting.

So I started looking into this about a month ago... and I started doing the newbie routine for 2-3 weeks and I saw a .1 inch gain in length. Then I injured my foot, and took a break. However, during this time I still stretched during the shower etc.. and I noticed my penis head is starting to feel cold. I was having trouble getting a hard on for 2 days or so but after taking a one week break it got better. Now I can get boners just as easily as before.. but the head is still cold. Should I be worried? How long should I continue to take a break? I looked over the forum to find answers to my question but I couldn't find any. Any help would be great!

thanks!
