I don't dislike tongue piercing. It can make you look a little reckless so you should be ready to be considered 'unfeminine' by some males who like shy neat girls. but there is nothing bad about it.
there is nothing bad about piercings in the whole. you should just consider if they look good on you or not and which part is better and also consider the dangers of it.
It's not about being attractive in everyone's eyes it's a style and a styles are liked by certain groups only. so instead of doing it to attract people do it if you yourself want to and like to have that style and consider the dangers of getting them too. I have dimple piercing and had nose piercing and my dimple got infected one time and it was painful. I can't imagine how would it be if it was my tongue.
