Is it normal masturbating to my friend's facebook pictures?

I'm a loser and I'm friends with this really hot girl, but she doesn't want to be my girlfriend. I asked her so many times if she wants to go out with me and she says no.

When I'm feeling horny, I go to her pics on facebook and masturbate until I release a powerful explosion of cum, and I pretend having sex with her which makes it feels 100 times better. Is this normal?
