I kind of think attraction is irrelevant when you love and are attracted to your partner. You can ogle at whomever you like, you just can't touch. (unless you and your partner have a mutual understanding in regard to this).
I like looking at women, some are absolutely smoking gobsmackly hot. I've even had crushes that felt like love on other women while married. Should I cheat because of this? Absolutely not. It's natural to be attracted to people you are attracted to. Being in a relationship does not stop you being attracted to other people.
Have a perv, fantisise, maybe have a moderate use of porno, but remember who you love. If you don't love them, maybe that should be the focus.
