The tampon would become very gross very quickly given as poo and bacteria are inside the anus, and that's not nice to leave laying around in a bin after use. Tampons will potentially damage the mucus membranes within the anus, thus resulting in possible pain and risk of infection. If you want to masturbate with anal penetration then use sex toys designed for this purpose, it's much safer.
If you are a 12 year old [cis] boy then you do not have a vagina to insert a tampon, nor do you have a uterus to menstruate, thus you cannot try tampons.
