People with desktops like that are usually young boys who never touched a real woman. Go to any gaming forum and you'll see endless avatars, banners, etc of "hot" women... usually used by 12 year old virgins.
If you're speaking to me, I have a gf and she knows my wallpaper and she likes it herself.
Unfortunately, you sound a little bit like a gay, with all seriousness. Judging that from you're a man and you like girls, yet you still moan about having a girl on your wallpaper... How that sounds?
You also could be an feminist, that one would make more sense than now actually.
Nah, i can tolerate it, but i was never fond of having pin-up girls plastered all around the house. Guess i never understood those construction workers with their sexy calendars on the walls of their containers. To me it screams "cheap" or "virgin", but hey... one mans trash is another mans treasure...
