What is your opinion on piercings and tattoos?

Well i want to get two tongue rings and a tattoo or two not now im only 17. But somewhere along the road ( maybe 18 19 idk yet). My brothers tell me that imma get it just to show off, and its gonna make me look easy (not like they are gonna make my decision but i dont want everyone else thinking that too!!!) but my sister is all for it. (well i didnt tell her yet LOL but i know she will be!) i dont want that to be the case (what my brothers are saying) but i dont want it to flash it all around ( at least that not my only reason) its just something i want. like my extra ear holes I wanted them theres alot of other people that have alot of ear holes and if i wanted to show myn off i would get more but i want them because its what I wanted not only for show. i mean i know its not gonna feel good at first but hey my ear holes didnt feel good at first either. Most boys think that girls with tongue rings are easy but im not….do you think that if boys start noticing my tongue rings when i get them that they are gonna treat me differently? im a nice quiet girl but i dont want me getting a tongue ring make me look like a rebel. and if i get a tattoo or two people wont get a chance to stare at those because those would be well hidden. what is your opinion about piercings and tattoos are they too wild? for someone like me i guess.. :-)
