People that don't do their research before trying certain sex acts

I feel like I'm surrounded by idiots in my friendship group.
They see stuff in porn that they wanna try despite never doing it before, they try it, and they wind up hurting themselves.

Of course you couldn't take a whole fist in your butt. You've never had anything in your butt dude.
Of course you couldn't cum bucketloads of cum like the guy in the hentai. That stuff isn't real.
Of course you can't take a large unlubbed strapon in your butt without lube or prep if you've never done it before. No wonder you're in the hospital with it stuck up there.

All these people had to do is take a few minutes to research these things on Google but nope, they just couldnt be bothered. Are they normal?
