Ok i dont know how normal this is and i think its time to go check this out because ive been reading all these different forums and all i can get is the preliminary hints to a serious penis disease, unless prevented. Now, when i get erect, at the bottom of the shaft, if i bend it far enough towards my stomach or the opposite way, i will feel a crack inside of it (just like crackin my knuckles or neck or chest; which i dont think is healthy either and i can do all of them!).. Now this crack actually feels REALLY REALLY GOOD .. i feel like i just busted a nut lol only for 5 seconds though, then its gone. I don't know how weird this might sound, but ive asked all of my buddies and only one of them (who's 30) seems to relate. Hes livin fine but caca i dont want to let this keep happenin and then 5 years down the road - IM LIMPDICK.. hell no! my penis is above average size (between 7-8") and i dont want that to decrease or become something im gonna have trouble using OR GET IT AMPUTATED OR SOMETHING lolll so please if anyones got any clues, any advice or any type of information to this kind of stuff, pls let me know because im absolutely CLUELESS and i dont feel like waitin 2 & 1/2 hours to see a doctor unless im 100% sure its gonna medical question me up!!
