Why are you guys all trying to use sites made simply for fucking? Fling.com, cams, and all that can be counterproductive if you're framing the e-mails and your ad as someone who's legitimate. If you want them to be your Valentine, wouldn't you take them along the route of what a Valentine does: flowers, a legitimate dating site (match.com, eharmony, etc) and whatever other sites you can find on your CPA networks because you don't just have sex and hookup all Vday, you go out, you do "romantic" things and then you get to it. Coming on that strong can undermine all your ad copy as a nice, cute girl who suddenly turns into vicious slut after 3 e-mails; really? That doesn't happen unless you have extremely good game, these guys don't, they're on Craigslist. It might even raise the flag that it's too easy, unless they're going to end up on To Catch a Predator anyway then God bless.
I've read the ENTIRE thread and I only see mention of a handful of offers. I just looked through a few of my networks, there's a TON of dating offers to use, why saturate a few and lead them into converting you? Also, you can post more than 1 ad a day in different cites, start switching your IP/Proxies. You should be getting1k/responses a day if you post 5 ads during the day. If that stays up, you've just given yourself a large enough sample to truly test if your offer converts, not 20 responses that have no statistical value.
Lastly, spread out your earnings across accounts. rotate offers, use different networks and make sure that you earn what you want, but that you send the traffic to a variety of sources.
