Hi, I really appreciate your concern about the delicate matter. As a physician I would like to answer all your questions one by one
Q.1 : The stitches used are Catgut stitches which will fall off gradually one by one. Also, the wound below them would close eventually but I advise you to keep it clean, take and apply your medicines and keep looking for any signs of infection. Everything will be alright.
Q.2 : You can apply the ointment to the area of
frenulum after taking bath, but make sure that the area is dried well and make sure that it is not kept wet all the time.
Q.3As your penis was uncircumcised for 20 years, your
Glans or head of Penis was covered in skin and was and will be sensitive for touch to normal touch of clothes. Give it sometime and the sensation will go away as the wounds of
circumcision heals you will feel better.
I hope I have answered your questions correctly and I wish you a speedy recovery. Feel free to contact for any further questions. Have a nice day.
Regards,
Dr.Abhijeet
