You are thinking like a nice guy and you need to snap out of it. Are you going to change your wallpaper to carebears and puppies now or what? don't be such a wimp!
Keep the wallpaper there. The reason being that it shows you like women/have adult interests/makes you seem more of a sexual being/makes you seem like you have an edge to you. Look at it this way. Who do you think will seem to a woman as more of a guy that is likely to be sexual? the guy with hot girls on bikinis on his wallpaper or the guy that has a wallpaper of some video game on there?
I remember how I used to seat behind this douchebag in class who came to class with a hangover almost every class. His whole look and attitude reeked of douchebag. He had a big o laptop with very provocative women on it with little clothes on. I thought to myself what girl would go out with a guy like this that is late to every class, looks like the perfect image of a hangover, has practically naked women on his laptop wallpaper and acts like if he were high all the time.
Right before my very eyes 1 time I saw him started talking to the hottest girl in class who sat close and he walked right out with her in the middle of the class. Same guy with the laptop wallpaper of women with little clothes on that would make a mother blush.
Don't forget that whatever you think is logical to do with a woman the opposite is likely to be the truth. That's how women are.
