Oh, I definitely used to be a collector. There could be a scene with a chick I was dying to see, download it and often times never watch it cause I was no longer interested in it/her. It was like as long as I had the file on my HDD, I was no longer interested in it. Bet your ass though, after I eventually deleted it, I would go looking for it to watch again, lmao. Laziness is what "cured" me though. With tube sites popping up everywhere, with seemingly everything imaginable, it felt like too much work to download a video, sometimes multiple parts compressed from increasingly shitty hosts, eventually I was just like, fuck it. Tube sites most of the time are good enough for me. I'm not picky, I don't typically need to watch something in HD, hell, if the scene and woman is hot enough 360p will work just fine haha (currently use a 1440p monitor). Another reason would be just losing interest in (commercial) porn in general. I don't watch almost any commercial stuff now and for years now. There's just a handful of women on OF whose content I like and even then I just keep the videos they're actually doing something like bating. There's just too much content out now to even try and keep up with it all, even from just a few ladies, it's overwhelming.
And speaking of wasted time on tube sites. Every single fucking time, I dismiss some video, not bookmark for whatever reason. Go back a day or some time later to find that exact video. IT'S NO WHERE TO BE FOUND! It's like someone is actively monitoring me and just wants to fuck with me for their amusement. No, not really, but it does feel that way sometimes.
Lastly. My view on public/exhibitionist stuff has changed over time. Could be because I'm getting older, I used to find it hot and once in a while still do. But overall I'd say it annoys me more than anything. I see too many videos now where the women seem like they're trying to be seen, or don't care. Maybe I'm being a little prudish, but there's a time and a place for things. You masturbating in a public space and not taking any or very little measures to conceal yourself is not it. Someone that's just going about their day, maybe even with their children, doesn't need to see that stuff.
