I rarely masturbate anymore, but when I do, I usually think about either my partner, or the porn I'm watching.

As for "condoning illegal activities" I hardly think talking about watching porn does that. We're talking about watching porn, as responsible (at least, hopefully) adults who understand that porn doesn't reflect what normal sex should be like. We're not talking about sneaking a look at porn on the internet as underage minors who may or may not understand the difference between sex in porn vs. what sex is like in real life.

To those underage minors who ARE watching porn (because we know darn well you're doing it regardless of what the law says), I don't have to condone it, but at the very least, I can tell you that what you see in magazines, videos or on the internet is a hypersexualized form of entertainment that does not reflect what real life sex is like. For that there is sex education, sex therapists and self-help books on sex (much of which is legally available to minors in bookstores everywhere).
