12 months ago i masturbated for around 9 hours with no lube , the skin on the penis got swollen and puffy and was bleeding from being chaffed so much , the next day instead of letting it rest i masturbated again and of course it got worse , the swelling did go down after a couple days but my penis hasn't been the same since , is extremely desensitized touching it feels like touching a callous you know you can feel it but there is zero sensation , the skin has been loose and wrinkly in a way that i have never seen, its lost all of its elasticity, it just doesn't feel good at all to masturbate anymore . its so depressing i feel like killing myself im 20 btw
What have i done ? should i see a urologist asap?
