who are we fooling here? i cant imagine for one minute that kevin has an out-of-control sex addiction regarding self-gratification and that this has not effected his computer use. that stuff is everywhere.
most obsessions/addictions have a threefold cycle. its the old sex/drugs/rock&roll syndrome. in this case, i am picking up on sex, food, and the third would be the two sided coin of drama - his parents nagging him on the negative side and the p 0 r n o g r a p h y offering escape on the "positive" side.
i could say more but it would be based on pure conjecture and sound downright cruel. if i am wrong, bury my post under the nearest rock.
