Yeah but, sex scenes in movies and sex in porn are hardly even the same thing. They're so wildly different, I don't see how one could be a replacement for the other.
When porn was less accessible they could definitely be in the realm. Now it's more often bad soft core or HBO style taking up too much of an episode without moving the plot.
True, but they can still get you (especially during Puberty) horny.
I think thats what these kids are actually complaining about. They're used to getting turned on and immediately being able to satisfy themselves on their phones. But during a movie they've got to wait another hour before they can releave themselves and that's frustrating for them.
Growing up my friend had a special VHS tape he'd rent movies and record the sex scenes to. He was pretty sheltered and just didn't have access to much else.
I guess it depends on the effects action could have on you.
If you're the type to get really pumped and hyped at action, something you do enjoy but maybe not all the time, then inserting it into a movie that you wanted to give you some other emotion would take away from the overall experience because it's hard to get out of the juiced up state of mind.
So if sex scenes make you horny, and maybe you're conditioned to get immediate relief from that feeling because of porn, then I can see why that could hinder your enjoyment of the overall movie.
