For guys, it's a different story. Men think about sex and other women all the time. According to AskMen.com, whether they are single, engaged or married, men think about sex every 5 seconds and not always with their partners. And most men, when they look at a woman automatically think about what she would be like in bed. Sad, but true, ladies! So the point is, don't believe your man when he tells you he doesn't think about other women.
