A short frenulum can result in pain and even bleeding during erection and intercourse, and in some cases, the frenulum may rupture and tear during sex.
A milder frenulum breve may go unrecognized, since foreskin may retract over the glans variably.
This is normal and will stop in a few days.
If you have to do it 4 times as I did you will be far happier with the results.
If you tied it really tight to cause pain and discomfort then it sounds as though you had enough tension.
The pros: Your penis is more sensitive so if you get cut, you will not have the same sensitivity, this will over a small time of recuperation make it so that you are able to have sex without the pain and irritation.
It did, however, take some time to psychologically feel ready for sex again.
It can occur in both circumcised and uncircumcised men.
