I guess I understand the need to be weird. And I guess I could understand how it could add complexity to a certain type of lovemaking (although it seems an unnecessary addition, but that' s just me).
But I hate watching someone play with their new tongue piercing or clicking it against their teeth. It's not a "fingernails on the chalkboard" reaction like my wife would have to someone hitting their teeth with a fork. I've been known to tap my front teeth repeatedly with a fork to irritate people. Not to irritate my wife though, I'm not stupid.
Plus I'm scared of the pain of getting my tongue pierced. And infection. And loss of proper enunciation.
And I'm something of a spaz (my lovely wife thinks so, at least) so I can see this happening:
And that's just plain embarrassing at the ER.
Oh and check out Tricia's blog. I don't now if she has any piercings but you could ask!
