you are casting judgement on pointless things. you are much like another friend of mine, and that is fine, but what you find attractive is not the same as what another person finds attractive. you do not know my reasoning for tongue spitting and I will take the time to inform you that is is for neither of those reasons. It is for the purpose of sound, as I was born with a condition known as Synesthesia. I can feel all sound as if it were touch, and the sounds one is capable of making with two tongues is fascinating and delightful to me. the piercings were an accident and are completely and 100% able to be removed without trace of them ever being there on the outside. I wear them with my cosplay because it helps people recognize who I am at conventions and on the internet and such.
I hope this has opened your mind in a way of thinking about the reasons people have for doing things. I understand some people do it for reasons such as being cool or attractive, but that is not my reasoning and I would appreciate if you did not assume so.
