Look But Don't Touch!

I was looking for a book and i found this pictures laying around so i start to look at them and i found this picture off this guy that i found to be really hot i took the pic along with the book and i "looked" at it allot so i finally decided to ask who the guy was and i found out its a picture of one of my cousins i haven't seen the kid in like 10 years so i didn't remember him so i felt bad and put it back but i cant stop thinking about it is it as wrong if i look at it but just don't touch the real thing?
