I've always hated it. If I want to watch sex scenes I'll just watch porn and not some softcore Hollywood garbage. It adds nothing to the movie/show. Just makes it awkward when you watch it with your kids or parents.
Honestly, it makes sense to me that the generations that grew up with the internet and basically limitless access to porn would be less interested in gratuitous sex in the rest of their media. They don't know what it's like to rewind three seconds of a tape over and over because of a single out of focus boob, or making do with the lingerie section of the sears catalog. They don't have that any port in a storm mindset.
I'm not that young, I grew up with VHS tapes and remember what it's like. Times have changed, it's not a requirement to be stuck in the "good old days".
