I don't usually save porn on my PC, only if it's something I think a mate might enjoy; it's easier for me to find it instead of searching some badly designed site.
I do have about three DVD's too, although I don't know why because it's much easier to find things on-line. I've not watched any of the DVD's for years.
Most of my porn is on-line. I'm a member of a couple of sites, and they update weekly. So I just log on and go through them to see if there's anything interesting.
Can be expensive if you don't keep track of them or if you're really horny and they haven't updated. Occasionally I find myself looking for a new site and then forget to cancel an old one.
I guess the best thing to do would be to rotate between them, and then you can catch up on all the updates, but I'm not that organised.
