So much to reply to.
Okay first off, no offense taken Gem. There's a difference between telling me I'm full of crap and being skeptical. It is a bit hard to swallow when you've been told porn's nothing bad for years.
On porn leading to pedophilia. First off, people are responsible for their own actions, no matter what contributing factors there are. That being said, porn can be a large contributing factor in any sexual offense. It works the same way drugs do. Watching porn causes a chemical response, one that is quite different from true intimacy and there's only lust and no love. This feeling is a positive feeling and one that people enjoy, or at least leads them to masturbate, which causes a positive feeling. Well, just like any drug, your body can come to crave and even depend on these feelings and chemical reactions that only come from one source. As time goes on, the body and mind grow accustomed to these images and feelings and they don't produce their original result. Therefore, it takes stronger stimuli to produce the same reaction. This can lead to more deviant porn such as beastiality, gay, hard core, and child porn. Once these not longer work, the addict sometimes turns to actually living out these fantasies. This is what leads them to commit rape. However, I don't want you to take my word for it. I've seen some former porn addicts who have been released from prison for rape who now travel the country telling people of the dangers of porn and they all say what I've just stated. That being said, there may be some people who can look at porn at it won't effect them in that way. In that fashion, it's like alcoholism. Some people are susceptible, some aren't. I, personally, don't find it worth the risk and porn can have negative effects on people who don't get addicted, too.
Final response: Here's the reason porn causes boob jobs. Men look at porn. Porn is typically a bunch of bimbos who have been either digitally or surgically enhanced to make them more sexually attractive. This sets an unrealistic standard for them men, who begin to be less than satisfied by their own sexual relationships. Their wives/girlfriends then go out to get boob jobs so they can try to live up to those expectations.
