Welcome to HCM.
You just ignore the presence of tag like flap. It is just the remnant of the torn and healed frenum of penis (the link between penis to foreskin)
Once the healing of the wound is complete and as long as there is no pain, just ignore the presence of the skin flap. It will not harm you or your partner. It would be highly unlikely to be a wart
and confirm the same by a physician after a careful examination.
