I was masturbating for around 4 hours, go me. but after i notice that i now have a lump under the skin. its firm but not discoloured. its a bit sore. what have i done to myself? is it just like a friction blister under the skin or something like that? when will it go down? i've put some frozen suasges on it to stop swelling. ha ironic...sausgaes...weiners....ha! keep on smiling in the face of your problems.
were you using any lubrication or friction reducing objects? I would think it's just fluid retension from too much friction if you didn't use any of the above. Nothing to worry about... happens to the best of us. Just make sure you keep the frozen sausage away from your testicles. Getting them too cold can damage them!
