<human>: Can you summarize the given text in a few sentences?

So, my brother is 2 years older than me (lets call him Joe), and we have another brother who is 4 years older than me(his name shall be Steve). Unfortunately, Joe is very shy, and always has been. I am a pretty out going person, almost exact opposite of Joe. Steve isn't shy, but is only out going when he is comfortable.

Steve and his first girlfriend in the past year, and I had to give him advice, because I've dated girls and knew more than he did, whatever. But, Joe is too shy to talk with the ladies. Its sad, but it is his choice. He likes to masturbate, which is fine, but I think I may have found a problem.

I like to scare the shit out of Joe, like hide behind his doors and make screaming things on the computer. I have found a lot of things on his computer. Sad things. He doesn't have a facebook for himself, but he has a fake one, that has his birthday and is one letter away from our last name, kinda obvious.

I'm concerned because, simply put, he masturbates to pictures of nearly everyone I am friends with. He downloads their pictures, and faps. He sets them as his screensaver. He even records himself fapping, I don't know what he does with it though.

I Want to help. I love the kid, but honestly, I'm scared. Its gross to see that my date is his friday night fap. I want to tell my parents, but what do I say? I can't confront him, because he likes to play the game where he acts like he doesn't know what your talking about.

I know his password for his computer, but not facebook. I've tried deleting his facebook when he forgets to log out, but facebook lets him re-open it.

So Reddit, how can I help my bro get some confidence, and stop fapping to my friends. How do I tell my parents, how do I talk with him about it. He's going to college and I fear that he might become extremely depressed...
<bot>: My bro faps to my friends, and its gross. I got myself a hotty for a date, and thats his friday night fap material. What can I do?
