Think about it, you get to see incredible hot women getting banged for like 30-40 min, and do things most of them wouldn't enjoy in real life. Basically, it twists your views on what sex is. Personally, I think that it makes you feel less "aggressive", and more desperate, also you see regular women on the streets and you subconsciously think they're not worthy because they don't look as hot as the women you can see on video. That's messed up.
I guess it's not that bad if you watch it once in a blue moon, but watching it everyday def takes a toll on your mental health.
