It is normal that i feel attracted to my friend's boobs?
I have a female friend that have huge boobs. We're just friends, she is not interested on me, and vice versa, and sexually talking is the same, we don't feel any kind of attraction for each other. However when I am with her, I can't avoid watching her tits and I start imagining a lot of things. But she's just my friend and I am afraid if I am a perv or is it normal?
