Still photos are much more common than 'sex tapes' in the relationships I've been in, and they've all been digital. I've never worried about anything ending up on the internet after a breakup---I wouldn't be giving pictures to a guy who was that unscrupulous. On top of that, I've never had a tumultuous breakup, nobody's ever wanted "revenge"... ugh. I shudder to think of being in that kind of situation. Never going to happen to me, I am attracted to level-headed and kind humans.
The only time I was scared was when one ex-boyfriend had his camera (with, yes, live 'sex-tape' type stuff) stolen. (His laptop was stolen at the same time, and that had plenty of pictures too, but it was password-protected and set with a remotely-brickable program.) He told me right away (even though that was somewhat recently after the breakup and we weren't really talking much), and we both crossed our fingers that the thief was more interested in the hardware than the data on it.
Two years later nobody's called me up to tell me they've seen me naked on the internet, so luckily even the thief had scruples (or was too stupid to figure out what to do with it). If the worst had happened, I'd be really sad that I couldn't run for president without being the subject of a "sex tape scandal." But, at least I know I can trust my former partners.
