Hi, I'm 13 and I've spiked puberty about a month ago (my voice just started crackling and I've already grown a half inch taller). I've been losing a lot of weight too and I've been exercising like crazy to get skinnier and gain more muscle. So as I go through puberty does the weight loss and muscle gain have any effect on my penis growth through puberty. Right now I'm about 6 inches in a hard state. I also noticed that there is a red spot at the head of my penis and it hurts when it's touched. There is also a vein type of squishy lump buy where the shaft and head meet could these two things mean anything? I've really worried.
nothing changes the size of ur penis,masturbating,pills,pumps.The only thing that makes it change is surgery and growth.Maybe u have an infection.I would advise going to ur doctor or talking to ur parents.
exercising is good! penis size is dictated more by blood flow then by other factors. a really athletic man like, lets say, an endurance runner, should have a larger penis than a lazy couch potato. if you are active, and eat healthy, your penis should be bigger, although it may not look bigger, it will have grown in width, or in length.
