Yes it is and this oversexualised society with music videos and advertising doesn't help. A lot of girls 'advertise' their wares anway. I can understand why a guy would look at some hot,young blonde mama in a mini-skirt. I don't like it one bit but that's life. We women will be jealous of other women, younger and better looking for eternity.
I don't get mad until women flirt with my husband right in front of me.
I don't know about "we" being envious of younger better looking women.
I guess I am really old here because I love young good looking women. They are like beautiful young animals all energetic and cute. I have three daughters in their 30's so maybe that colors things. But I love looking at young people, men and women,,,they sort of make me feel happy.
And my husband having had three daughters adores young women. They sort of flock around him and he just loves their attention, they make him smile, nothing lecherous about him. I think he just has joy in their being young and beautiful and sweet. It is one of his most endearing qualities.
Maybe we are just old and beyond envy and such.
