Just over a year ago I had a frenuloplasty performed to lengthen my frenulum (it was short, and thus prevented me from fully retracting the foreskin whilst erect - frenulum breve). Now days, I can fully retract my foreskin, but doing so pulls on the glans. It looks very much like this picture: Imageenis eregiert.jpg - Wikimedia Commons When masturbating, the glans almost appears to 'nod' because of this. Is this normal? And, if not, will I have to have a second frenuloplasty performed the fix it? Any help is very much appreciated.
