What a variety of responses in here. Fascinating the ways people look at this.
I don't see how you can not notice hot people. I think it's fun to point them out to each other. Usually we crack each other up over it.
Maybe you need to find someone who's ok with it...
Looking, not ogling.
Make it fun. Start pointing out cute guys to her. Notice how she doesn't leave you for them. See. It's a process. You're feeling compelled only because it's not 'allowed.' Don't sit there and dwell on anyone's parts or anything. Just show her how cool you can be about it. Like, give her a compliment afterward. Change the subject right after. It'll reinforce to her that it's no big deal.
In the final analysis, it comes down to this: When you appreciate a slice of pizza, does it mean you don't still love steak?
I mean I like ice cream.
...But not every night.
