Hi I was on my commode and my penis was under the commode hole. While watching some porn from my phone, suddenly I noticed that my penis was erecting. I was trying my pulling my penis from the commode hole and noticed that a small lymph was growing on my penis shaft near the balls. I was scared and thought that there might be problem on blood circulation. Tried to massage softly but not changed. Then I did my masturbation to see whether it will vanish or not, but it is still as it was. Now I am thinking that masturbation wasn t a good idea on that time. Need help to get rid of that lymph and really scared for this. What should I have to do for that? Can you help me please.
