Moreover, having long distance sex, is a great way to keep the sexual spark alive between you two.
I've had a wealth of sexual experience, and learned many wonderful and terrible things from many wonderful and terrible people.
Having an encouraging person on the other end is invaluable. (Am I just a set of naked pixels for you to put your sex feelings into? Since you're clearly not near your partner, a little keepsake for the lonely times is nice.
If my partner weren't reassuring me I was hot, it would just make me feel weird. ) It's scary to be that vulnerable, so make sure you appreciate your partner out loud. But before you take a screenshot, make sure your boundaries are clear.
(Granted, if you're really a criminal mastermind, you could crop it out, but let's call it a deterrent.) Mostly, don't be a dick. You can always opt out of including your face in the frame.
That way, if anybody else sees it, you can deny it, because it's just a bunch of faceless body parts floating around on a screen. It's widely held that men are visually stimulated and women don't know how to use their eyeballs except to look at shoes and children and housework.
