As far as causing any venereal disease is concerned, I haven’t come across any such issues related to penis enragement procedures.But if you are keen to proceed with this procedure I would suggest you to consult your urologist or you can even request for consulting an urologist. They can best guide you on all the procedures related to penis enlargement. You can very well trust them for your questions as they are expert who deal in this field.
