[NSFW] What do you do differently in video sex?

First of all, by “video sex,” I mean seeing and talking to a partner over the internet and engaging in mutual stimulation with the aim of having deep intimacy (and usually an orgasm as well).

Obviously, there are some taken for granteds. Video sex over the internet is all about sound and sight, but you can’t touch. Since you can’t touch, that changes the way you go about it. But how does it change it? What do you do differently? What tricks have you developed? What do you like about video sex that isn’t available in live sex?

It probably helps in answering the question if you have actually had video sex, but I know that won’t stop anyone who has never tried it from answering.
