You have to understand, this is not necessarily a bad thing, even though it may seem like it. Men are hard wired to be visual in a way that notices certain types of movements. Bouncing breasts and swishy walks are two of those types of movements. I (very, very straight man) have caught myself looking at a mans ass before (MULTIPLE occasions) because he had that way of walking. Embarrassing, to say the least.
In short, it has nothing to do with how "good" you are. He notices because noticing things like that is a survival instinct for men. It's no different than how women have better color vision on average - during our hunter-gatherer days, women had to be able to tell which red berry was really tasty and which one would kill you if you ate it. It's no different than how men can handle 3D mapping in their heads better, on average, than women - a hunter does a much better job of hunting when he can figure out the strategic and tactical advantages the terrain gives him.
Love has nothing to do with it. If you try to make him deny that instinct, one of two things will happen - he'll succeed, and wind up so tightly wound up from constantly and at all times making the effort to keep that portion of his brain disconnected, that he'll be a totally different person, or he'll fail, and you'll be pissed. About the most tenable middle ground is to ask him, not to stop, but to RESTRAIN himself from rubbernecking. Which is fair. The glance is the part that is hardwired, not the twist of the neck or drop of the jaw. So go ahead and ask him to do that much, because that is fair.
As you might imagine, there isn't really a thought process associated with this - no nudity picture, no nothing really. There's an old joke about a guy on the beach looking at the girls, and saying something to the effect of "Nice scenery". That joke is overused, but it's got a kernel of truth to it. If you open your eyes to a beautiful sunset, you can't help but admire certain aspects of it - light shining through the trees, the play of the light through the clouds culminating in shades of amber and lavender across the horizon - so on and so forth. That is, quite literally, how we see a nice ass or a good set of boobs. It can't really be helped. Take it as a sign that your man is virile, and stop obsessing over it.
Hope this helps.
