(CNN)  -- Dylan Ryan and Danny Wylde knew each other online -- she's read his blog, he's seen her tweets -- before they met in person in Los Angeles a few weeks ago. A bit awkward, they made small talk, spending an hour or so getting to know each other. "When I'm with someone new, my primary bit of nervousness is I have no idea if they'll like me, or be attracted to me, or be interested in me," Ryan says. "It's sort of akin to a first date situation." But this wasn't a first date -- it was strictly business. After chatting, Ryan and Wylde got to work, which in their case meant having sex. Ryan and Wylde (their stage names) are adult performers.
