Big boil after PE session.

After a newbie routine session I did resently, I got a big boil, filled with blood ofcourse. It´s placed under the string behind the penis shaft. The lower part of the foreskin seem to be longer and thicker than the upper part.

Is this normal, and will it disappear?

Am I the only one this has occur too?

This is pretty normal and I’ve heard it happen to quite a few people. Sounds like you just went a little too hard for your penis in its current conditioning. Take some time off, heal up and then come back at it again gradually.
