Here's the problem with this whole shit as I see it.
Everybody has a past. Nearly everybody done fucked somebody they don't want anyone to know about or been in a smutty ass sexual situation at some point in their life; we get that.
The difference here, however, is we can see the shit. This chick's smutty past is out here for everyone, including her new man, to see. If it was just some live shit you did and nobody knows about it or had pics or video evidence of it then that's one thing. You go on about your life and can deny said event even took place or you could bring it up but downplay it like it wasn't a big deal. But we can see it, and it casts a whole new light on her especially if the video or pic is a complete 180 from the image she projects.
There's a number of pics floating around in this vein and I know I have several of them stashed and I'm too lazy to look for 'em, censor them, and post 'em but basically it's usually of some professional white broad or some chick singing in the church or something like that and beside those innocent ass pics is one of the same chick gettin gangbanged by a group of Black men or whatever. What happened behind closed doors came out for all to see and immediately changes the perception of that chick. Same thing can happen for a dude. Yeeears ago there was some anti-gay politician or something that got his whole world fucked up when a pic of him crossdressing came out in the tabloids. More recently you have Wes Goodman, a staunch anti-gay Ohio state legislator that got caught having sex with another man in his office and there's supposedly a number of pics and videos of him out there. Dude went from Mr Wholesome Midwestern Husband to Gay Homosexual Sleazy Slutmonkey fast as shit behind it.
Bottom line: your past is only in the past as long as pics or video of it don't surface, then you gotta deal with the shitstorm surrounding it once it comes to light.
