Hello, first i want to say that this site is perfec for PE

You can find anything you need to begin with PE, and you don't need to look around... it's perfect and so simple to understand...
Second, I want to say sorry because my english sucks
Third-my problem :
I was doing my newbie routine (first month : warm up,10min manual streches, 10min wet jelq, some kegels and warm down)... in my second month i move to the 20 min of streching and jelqing (with stronger grip) and two days ago i saw something just behind my glans. I don't know what it is but i found picture on the net and my penis looks exactly like that. I don't feel some extra pain because of this, but i stopped with routine. Please help me, is it thrombosed vein or something else ? What should i do?
Thanks guys
