I caught my husband (early 40s) looking at teenage girls a few times when we're out.
The girls he looks at are usually wearing mini skirts, shorts or have their breast out.
They look like there are between 15-18 years old.
I remember when I was around 14, I had a few men staring at me even though I always dressed modestly so I'm starting to wonder if that's in men's nature.
I asked one of my friend who's husband thinks his behaviour is normal. That every men are attracted to young girls(15-18) with boobs or nice legs even if they don't want to admit it. It doesn't mean that they will act on it.
