in all honesty, once all you little tweeners mature, and get a girl you really dig, you wont understand. its like a nice play, there are multiple acts, an intermission, and a grand finale.
also to all of the ppl that said they wouldnt kiss a girl after she give u head, you kiss her after you go down on her, why not kiss her after she has gone down on you. You all need to get past the whole penises are gay bullshit.
