I'm a decent looking guy and usually date pretty good looking girls. However, recently I've been dating a girl who is pretty plain-jane, really not very hot at all. She's not ugly, but I don't think she's really ever turned any heads. We get along really well, laugh together, enjoy each other's company, but I'm finding my eyes wandering a lot. It's as if I see as nothing more than a friend, but due to the fact I'm a guy and have sex with her because she's willing. And even then I often have to think of other women in order to climax. It's terrible. I feel bad.
Anyone been there? Advice? I guess this must be how marriage is after 10+ years, huh?
