Is my son wallpaper ok?

He's 14, he and his friends probably look up much worse things in private. It's better I think to just have it in the open, so he isn't afraid to talk to you about things like puberty and girls. It's not the whole 'cool mom' thing if you leave it up. But nobody likes to feel like your controlling what they can and can't see, and a teenager, especially a 14 year old will see you being protective as an attack, and they'll lash out like it's North Korea and you don't let him read or something. Or maybe he won't, everybody's kids are different. Boys will be boys, it's just a picture, it's not like it's a swastika. He's bound to see a pretty lady like that at some point, wether or not you let him see it just shows wether or not your ready for him to be a grown up. A lot of parents play out their insecurity's on their kids. My mom was never a good cook, I loved her to death, but if I told her that I wasn't hungry she'd send me to bed without dinner because she was insecure about her cooking. Some parents are insecure about other things, like attractive women, I'm not saying all moms aren't wonderful beautiful people, but when you sacrifice your body to have children it's hard sometimes to be around or see attractive women because you don't feel that confident. I think you should just leave it, he's already seen it. He's more likely to go looking for it and find even worse things if you take it down. Just talk to him about the birds and the bees, and set ground rules, like no looking up ographic websites or no girls overnight.
