You don't have to have personally watched something for it to affect the culture around you, Unsolved.
I agree, but in the 80s, the closest most teens got to porn was the underwear section of the Freemans catalogue. Those who did manage to get a copy of their older brother's Playboy or Fiesta, were few and far between. Porn was never driving the desire for teenagers to have sex and it wasn't influencing the type of sex they were having. But boys were still putting pressure on girls to have sex, to give oral, to do the things that they had in their head.
I am not saying that porn has no influence - it does, but it is not the driving force in the pressure that teens are under to have sex. Hormones drive the desire. Slut/Prude shaming - telling girls what they should and shouldn't be doing, makes it difficult. Along with the pressure on boys to hit the bases. None of that has changed since the instant availability of porn. And really poor communication because adults have so many hangups and morality tied up in sex, that it prevents the conversations from happening that need to happen. Blaming porn does not help. Removing it will not fix the problem.
how did you know that anal sex was a thing people did?
That is a ridiculous question! You are implying that people will only do things in bed, that they have heard about. There were plenty of people raised a few generations back, who weren't told ANYTHING about sex, but still managed to figure it out through experimentation. We had high sex drives, a lot of imagination and we did what felt good - simple as that. We talked about it and it was a positive decision that we would give it a try.
It gets back though to 'consent' and this needs to be hammered in much earlier in schools.
^^Yes absolutely. We need to talk about consent.
We also need to challenge the slut/prude shaming culture that has been around for a lot longer than internet porn.
