After some vigorous masturbation I felt like my penis had puffed up around the circumference so I stopped. That very day I noticed this had made a very soft and rubbery circle (and another half circle as well), encircling my penis, (prominent mostly on the sides) almost like I squeezed it too hard.

I’ve had no pain except for the discomfort that one time masturbating, all seems well now. And I have no curvature etc..

It is not noticeable when completely flaccid. but during a semi erection (when the penis is soft but still somewhat engorged) I can see a “ring” under the skin around the shaft. It is not movable with the veins

Anyways, I have had this for 2 weeks… I have no pain or erect curvature. Great erections… Just this thin soft/rubbery thin stringy thing that isn’t hard or obstructive.

Do I have Peyronies disease? Does it ever present this way early on?

Greetings, 

No, not much of what you describe sounds to me like early Peyronies disease.   It sounds like not much more than some inflamed and swollen tissue that should clear up in a short while.  If it does not start clearing up soon, say in another two weeks, I suggest you have it looked at by a urologist.  

However, let me put you  on notice, my friend, that any masturbation technique that is aggressive enough to cause that kind of tissue swelling and inflammation two weeks later might just as easily have caused Peyronie’s disease. In this sense I think you were lucky this time.  But, you might not be so lucky next time.  I have a feeling that you masturbate with some frequency, and perhaps even with some degree of aggressiveness.  This might be the reason your rubbery ring has persisted; I suspect you are continuing to masturbate  even though you have this bruised tissue ring problem.  While it is not my intention to tell you to stop masturbating, I definitely do want to caution you that you should reconsider how you are masturbating (and how often, since this gets back to the issue of being abusive to the delicate tissue of the penis shaft. 

Please lighten up and enjoy a slower and more gentle experience.  Peyronie’s disease is a terrible thing to happen to a guy.  You do not want to be the man who brought it on himself in this way.
