Does anyone else here ever feel that way? And, if so, how does one resolve the guilt?

No. Absolutely zero guilt. I simply enjoy the artistry of whatever god created the concept of human females. I, too, will position myself strategically to better, well, what you said.

Before I left prison, I made a rule for myself (to hell with society's rules) that I would never go out of my way to take photos of my attraction nor to actively pursue one or more of them. Should one enter my photo of some park's trees or whatever, I would not begrudge the serendipity. Should some hopeful parent ask if I could take a group of youngsters for a short sail around the Toronto Islands, I tell myself that I did not pursue and it would be okay.

But ever feel guilty about any of it? No. Imperatively not. Not any more. Never. I revel in such sights so long as it is not something I am actively pursuing. This, then, is the rule I made for myself.
