Hi everyone. I'm 16 years old (almost 17). Last night I noticed an itchy feeling under my skin of my penis. I pulled my foreskin right back as far as it would go as that's where I found smegma. I tryed to get it off with wet toilet paper and water. I had no luck and I found it awfully sensitive to touch, the smegma was hard and crusty (and for some additional information I was doing this when my penis was not erected, just normal). I thought that I will try it again later and I pulled my skin back up, like it normally is. But to my shock I looked at my penis to see that it was a bit smaller than usual and my raphe line (if that's what the long scar underneath the penis is called) was thicker and bulging out all the way along the line a bit, also there was more skin left at the end of my penis than normal and my pen is felt tighter than usual. I panicked and went to bed shaken up desperately looking for some answers on the internet. About 10 minutes later and with no luck on the internet for answers I looked at my penis and with my great relief I found that my penis was 100% back to normal. However I still have got to deal with my Smegma problem but don't want what happened last time to happen again this time. I don't stretch my foreskin. I was told on here that this was normal. However now I can't get an erection, whenever I try I just get the weird puffy raphe line thing. I have never had sex. Please help me. What's wrong with me? Thanks in advance.
