I think your mother made the right choice for you by having your little c o c k cut and trimmed. All boys should be circumcised. And yes it is her choice how she wants it done. So stop whining about it.
It is also her choice to have the anniversary date tattooed on the brown scar ring around your shaft. Every time you see it you are reminded of the glorious occasion and of her favor in having you properly cut and trimmed. Your mother must have a good reason to have your shaft tattooed with the date. Obviously it was what you needed. You should thank her.
