I think the Internet has ruined virility of many men of this generation.
I talked to my cousin, which reminded me of this topic. He just turned 18 and just got his first girlfriend. His girlfriend is not much of a looker but at least it's a start. While I was talking to him I just couldn't understand why it took him so long to get his first girlfriend. He's not a bad looking guy and he's funny and likes have fun with friends.
But then I remembered how he joked about fapping twice a day sometimes more...
When I was his age, I already had several girlfriends and I began dating at 14. But back in the '90s, Internet porn was still just a novelty. We had Skinemax and Playboys but they were mostly softcore and still left a lot to the imagination. Also they weren't easily accessible for most. Heck, I hadn't actually seen a blowjob up close until I got one for the first time.
I think not having a daily porn-crutch to satisfy your desires, encouraged most boys back then to be more aggressive and confident seeking women. Also when we finally got to the sexual act, it was more intriguing and gratifying because we hadn't watched tons of bizare hardcore porn so our expectations weren't warped.
I don't think porn or fapping is evil. But I definitely think it sedates the sex drive to an extent. Who knows, sometimes you want to sedate your sex drive (ie. your SO's hot BFF is staying overnight at your place :lol ) but if you're a teen and you haven't had much luck with women, you really should lower your exposure to porn. A lot of teens and young adults seem to use porn as a crutch. For example, they won't build up the nerves to talk to the Asian girl in class because they'll just rub one out to Japanese upskirt porn later that afternoon. And when you finally get a girlfriend you may have trouble performing because the bedroom experience isn't replicating your various porn fetishes.
I actually think it would good if people followed the warnings and only watched hardcore porn if they were over 18-21. Not because it's evil, but because it stunts a man's sexual growth and virility if watched excessively at a too young age. My 18 year-old cousin can tell me every single sexual act and position imaginable but he doesn't know how to undo a girl's bra.
