So many horny guys around me...?

Okay, now I don't like complaining, especially to you guys. But I am 13. And all my guy friends ALWAYS make horny/perverted jokes. I always have a comeback right away which always puts them over the top, but WHY do they have to be so weird around me? Jeezzz. And then I come on here...and guys keep flirting with me. :P Sometimes I'm just sick of guys. I think I'm glad a girl. :)
