For me, not making sense of a problem I have is not always the pathway to a solution to that problem. I have no idea why G-d created beautiful women that are available for me to look at. I just know that if I focus on "just looking" at all the women I pass in the grocery store creates a problem for me. Consistently focusing on how beautiful (or not) women I see in daily life quickly becomes a trigger that leads to a problem that disconnects me from G-d, my spouse, my daughter, my granddaughter and grandson, and, well, just about everyone in my world. It's not a total disconnect, but the diminishing love that turns to lust quickly makes me, quite literally, sick. If I act out, it takes at least a week, often more, to recover. I physically, mentally, and spiritually am "hungover" and certainly not nearly as available to others until I fully recover.
So, after a week of hell, it doesn't matter why G-d makes those beautiful women available for my view, what does matter is my always focusing on women, period. There are worlds of other people, places, and things I can focus on that does not lead me to "act out." My focus should be in that direction rather than on why I can or cannot look at beautiful women.
I'm not sure if this helps, but sharing this with you helps me at this moment to "guard my eyes."
