actualy i don't think about anything in particular... i just stop focusing on whatever 'sexy' thing is making it that way.... normally i don't give a shit, but it used to happen to me alot in school... you know, in junior high right about the time you start hiting puberty, and the girls start getting asses and tits... lol... god i hated those days... it'd always pop up right at the end of class too when i gotta get up and walk to my next class...
