So hey im a 21 year old guy and this morning i woke up and masterbated and yea after it was all well and good but when i went to the toilet a while after i noticed something different, my penis seems to have grown wider but only around the top area to the middle while the bottom is relatively the same thickness, i thought oh yea thats a bit weird and i decided i wonder what its like erect and same thing the middle of the shaft to the top was a bit chunkier than usual and the bottom looked very skinny it also kind of hurt when i pulled it a bit apart from that when i urinated it everythin seemed normal like i wasnt bleeding or anything. Since then i have been having weird feelings around the area and i can no longer pull the foreskin back i use to be able to pull it down all the way and now when its unerect it just bends and doesnt go back at all and when its erect it hurts and bend to the side. Sorry it is kinda of hard to explain hopefully someone understands what im saying haha.
you should definitely try visiting a doctor, they will help you figure out what is wrong
