Your tongue is not attractive. Keep it in your mouth.

Does this go through your mind when you're taking a picture?
Hey, I know what will make me look hot! Let me stick my tongue out of my mouth like some kind of brain dead idiot and show people my uvela! What kind of guy could resist that?!

.....What?
How could anyone think that's attractive? IT'S DISGUSTING! I mean, what are people supposed to comment to that shit? "Hey, nice throat"? Ew!

Seriously, keep your tongue in your mouth. It's not sexy. It's not even cute. It's gross and, honestly, makes you look tacky and slutty. Just, please, spare yourself the humiliation.
