Totally false, my friend.
First, you can’t speak for every guy, pretty sure. You can’t speak for me, anyways.
I appreciate beautiful women as much as any other guy, but what you just described is a very worldly way that a guy might consider a woman.
I saw a beautiful college age woman just 15 minutes ago. She’s devout, sweet, and has a pretty face. (95% sure she’s too young for me, though.)
I did not look at or think about her chest or back end but she is fairly trim and I always appreciate that in a woman. A good Christian man needs to see all women more in the way that God sees them.
I was also just thinking about Kateri Tekawitha at adoration this afternoon and how holy she was, pleasing to God, she had terrible pock marks / scars on her face from small pox as a child and so that really disfigured her. But how special she was to God. What a beautiful soul.
