Phrases like “couple this with” from this sentence from my first comment are how I’m breaking it down. The meaning of this is “in addition to” not “these are equals.” I’m sorry you’ve not managed to read the context words I added specifically for this purpose.
Couple this with how incredibly unhealthy the social relationships portrayed in most pornography are, and you’re gearing up for a lot of young men addicted to wanking and having unrealistic expectations of sex.
From my second comment:
The porn is rather a social knock-on effect because people often seek out porn to make the pathway to dopamine release easier.
Because it’s true that people use shortcuts to cumming, like porn.
