<s>[INST] Hi I have a tight frenulum where the head of me penis bends backwards when I pull skin down shaft. I was thinking of tying off frenulum but not sure how close to shaft I should pierce triangle as it has minor veins incorporated within it, should these veins be in the knot? [/INST] Thanks for asking in healthcaremagic forum   If it is causing you pain/inability retract then visit an urologist for examination and management. Do not do anything yourself. All the best. </s>
