To me, what I feel like they take away is valuable screentime. This opnion does hinge upon the fact that I feel most sex scenes are superfluous and don’t add anything to the movie they are in. To be honest, these seems to be further backed by the fact quite a few sex scenes are done at the behest of sudio executives and not directors, because they know sex sells, at least with older generations. I feel like a lot of younger people recognize this and don’t really care for a sex scene for the sake of itself.

This is all not to say I think there shouldn’t be sex movies. I do think it can be part of the plot and add to the narrative, I just don’t think that is always why we get one.

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.
