last month i woke up with a red lump on my penis after masturbating the day before like 3 times, i masturbate quite often, almost everyday multiple if not 3 times a day! i got tested for herpes results came back negative but i have no idea what it could be
a photo would be useful
it could be a lymphocele if appeared after maturbating its when lymphatic fluid gets trapped in the lymph channels it can cause a hard or squashy lump to appear usually goes away on its own but if u are masturbating quite frequently it may not go down in size unless u stop for a while
