Penis Size

Its normal your perfectly fine you just haven't hit puberty yet that's why you can't cum.. let me tell you a short story about my bro. when my friend came (known him since 3rd grade) we would always play around and stuff GAMES AND COMPUTERS (just so you know i'm not gay in anyway i'm a male and 15 soon to be 16) but one time when were showing off each others penis (i was 14 or 13 and i had no idea what the h*ll i was thinking) and my friend we both had big penis' and my bro (he is 12 now but 11 then) and his penis was like 3 in. my friend made fun of him but i tried to comfort him by saying it will grow in a few days... but he hit puberty when he was 12 and still is i caught a glimpse of his whilly whacker when i was coming upstairs to my room and it was about 5 in. last week i said i wonder how big my penis was (i was just playing but he measured his when he got just a little hard for actual size...) anyway he said it was 6 1/2 in. i thought to myself jeez that was a major size improvement .... but don't be discouraged by what you see or hear yours will or be bigger or the same when your their age
