James, I wouldn't say it's "wrong" but I wouldn't say its good or harmless either. Do some research on porn-stars and their legal issues. Generally, these are dudes who don't have much "normal" success in real life but happen to have a big pecker. So, they turn to porn, make a lot of money fast, blow it on drugs, alcohol and toys only to find out that in a few years they are again penniless with nothing left to show for it except social diseases, drug addiction, psych problems, debt and a huge, un-explainable hole in their resume. they make professional athletes look like angels!

All-in-all, try to keep your idols to people who value things that help your community, in the fields of business, science or education. Idols who can't give you anything back are no more that comic-book characters.

Good luck!
