I recently noticed a fairly large hard lump appearing to be just under the skin on the Under side of my penis shaft. I do masturbate sometime hard. I am only 19 and haven’t had sex yet so how did I get this. Any replies would be greatly appreciated
Unless you are sure the grip you use is the cause of your lump, I think you should get checked by a doctor. If you are sure it's your masturbation technique, maybe using a different hold (and being more gentle on yourself) will be enough to allow healing to take place over time.
It's hard to say without a pic, but it could be a lymphocele, which would normally fix itself after a few days rest.
If you want to add a pic, you need to be on a PC or laptop. If you are, then you should see some extra icons towards the top right of where you type, and the right hand icon (which I think is supposed to look like the sun over mountains) will add images.
The pic I've attached here shows the icons:
Even though I am haven’t had sex or haven’t even possibly contracted an STD I should still get it checked?
You might wait a week or two. but then, If no natural healing or improvement, definitely see a doctor,
If, as I suspect, it's a lymphocele, that is generally caused by rough sex or masturbation and will probably fix itself with a week or two, maybe sooner. Seeing a doctor probably wouldn't help, but if you do, please let us know what they say.
