I am 21 and I have not had sex with a girl in the last year
Last Sunday I masturbate around 4 times and now I have a lump on my penis
Its on the left shaft, its not on the skin, I think its on the internal (tunica albugina?) because when I move the skin the lump continue there
I have no pain when my penis is not erected but I have pain when its erected.
Colour its normal and I have a good hygiene.
What can I do?
Thanks

If you have pain with erection you need to see a Physician - pain is not a normal thing.

I have pain when is erected and I touch the lump

And, again - pain is not natural. You need to see a Physician.

No one can diagnose you over the Internet - and pain? A whole different category.

OK. Thanks

I have a similar situation, but I can not see a doctor for several weeks... though mine does not hurt, I think they might be similar, what did the doc say? If you don't mind my asking
