Thinking about others during sex

[Colorfulme]

I wanted to get some other guys opinions about something I've thought about for years. You see I've been in a relationship for 8 years. It's been fairly decent but for nearly a year I've been in counseling working though problems, to some success luckily

Is it normal to fantasize about other guys when having sex with your partner? If I'm truly honest with myself, I've rarely gotten turned by him. For this reason he usually has to initiate anything which is frustrating and leaves me constantly using porn to get off. It sounds so shallow but I don't find him cute. He's not my "type" necessarily in looks.

Luckily we get along amazingly and that makes up for what doesn't occur in the bedroom or even affectionately. I tell myself looks fade and a life companion is more important, usually that works. However I fall into this pattern after reading a book, seeing a movie, hearing about someone else's relationship, etc. that make me feel like something is missing. If anyone has any thoughts I'd be so happy to hear them.
