It's part of the nature of men.Women know exactly how to attract men's eyes.
The opposite thing happens as well.
Everyone get tempted at some point of their life, to resist just change your thinking.
Or do something that can revert your attention.
On the animal level a male human can get one or two women pregnant every day from age 13 to age 43 or even 50 then slowly taper off with age.
So as a male designed with a body that can do this managing the urge is important.
I know a guy with 23 kids. One wife and 19 pregnancies.
I would say he had a lustful relationship with his wife.
I also don’t think is was clever of him to make this many babies. But I guess he wanted to fornicate and his wife let him.
My self I am married since 1986 and I only go with my wife.
At 63 controlling lust is not a problem for me.
At 30 ,35,40,45 it was more difficult.

I'm near at that age that you have mentioned and I can really tell that the struggle is real. Doing my best to avoid those things and as much as I can it's getting harder since we're all just staying at home.
I have no plans of getting more than I have, one is enough. I just want to overcome this struggle.
