I've had wallpaper like this since I was single, and now my wife actually likes it as much or more than I do. She is bi (not so much dating women, but loves fucking them) so she likes looking at beautiful women as much as most straight guys do. Sometimes we'll be talking when I'm at my computer and I don't have anything open onscreen, and I notice that while she is listening to me, she is checking out the wallpaper. So basically I would say that to answer your question, you can either:
- Be single
- Be confident and not give a shit about peoples' opinions of you, or
- Have a confident wife/SO.
