Speaking from a mono view point, the comments that comes to mind "I may be married, but I'm not DEAD!" Finding other people attractive is NORMAL, just look at all the hype over certain movie stars. Is the gf religious? Is she from a family of all girls? I have seen this type of thinking a lot in the religious community and with women who didn't grow up with boys in the house.
I suspect some couples counceling might help maintain a mono relationship with this woman. If you do believe yourself to be truly poly (you want close intimate relationships with more than one person at a time), then it sounds like you may have a serious uphill battle if she can't even handle you finding beauty in other women.
