Why do boys want pictures of girls breast?

It's pretty simple whether there small or big boobs a boy is attracted to them. it's hormonal, and as the boy ages nothing will change, boys will always be attracted to boobs. Those boys will be even more attracted if you say to the boy he can't touch them. CuriOSity is what drives boys to do what they do, and having what they can't have. Boys can't have boobs therefore they are attracted to at least touching them, but like I said before they will be even more attracted if you don't let them feel your boobs.
