Should I have sex even though I have frenulum breve?

Yes you can. But could be painful and frenulum could get torn. Consider having frenulum divided. This can be done painlessly in a urologist's office. $% Lidocaine cream can be applied to numb area, 30 minutes later small amount of Lidocaine plain can be injected painlessly under skin just below frenulum which is the clamped & divided. This frees up penile glans & is sutured vertically with absorbable catgut.
