Sorry to hear that your friends and acquaintenances are irresponsible reprobates. Many of us are not and resent busybodies like you.
Frankly I don't give a flying you-know-what about what you do in the privacy of your own home. It's none of my business. What is my business is sharing the fact that it IS harmful in many circumstances.
Btw, I was speaking of two people who are parents of our 7 combined children. The addiction to porn didn't happen overnight. With my ex, the first thing he did when cable became available, was to sign up for the Playboy channel. When VCRs and video tapes became available, he amassed a very large collection of porno tapes. Not only was I disgusted by having to sit through some of the grosser ones, we were late on our bills, and I had to make do with little money for groceries. You see, my ex was screwing around behind my back the whole 19 years, and dating is expensive. It really went nuts when we got our first computer, and online access.
My bf's business is his own, and I'm not going to share how devasting his ex wife's porn and methamphetamine addiction has been to him and his 3 kids.
You can just go to hell.
