Lynn delves into the nitty-gritty of sex as well as the abstract. She devotes a podcast to the disposable sex toy trend, reviewing a $7 one-time use "masturbation sleeve" and throwaway vibrating rings that spice up sex while keeping it safe. With more disposable sex toys on store shelves, Lynn hopes Americans will get over the stigma of bringing gadgets into the bedroom.
"Toys are one very tangible way that we regular people do see the marriage of sex and tech in ways that just really brings it home for us," she said. "We can't all go out and buy…cyber sex suits but everyone can have a little vibrating ring."
Because Lynn's a writer by trade and not trying to hawk products, Doolittle believes she's a credible source of information.
"She has really kept her pulse on how the Internet affects sexuality," she said. "It's an interesting twist because of where she comes from and she's not trying to sell anything."
And Doolittle speculates that Lynn's appeal comes from her image as a sexy techie.
"She's a real tech dork," Doolittle said. "You always have this picture of the spectacled sexy librarian -- she embodies that for me. It's like, 'Oh, this geek is so hot!' It's just a stereotype but it works."
But sex advice podcasts aren't just for those who have to have their WiFi with their foreplay. "Sex Is Fun" has been podcasting frank, vivid discussions about sex and relationships to listeners all over the world since 2005.
The show features its creator and host "Kidder" weighing in on a variety of sex topics with sex educator Laura Rad and audio engineer "Coochie."
Episode topics range from the traditional (long distance relationships) to those that would likely be banned from the mainstream airwaves (strap-on harnesses). The show also devotes episodes to answering listener questions submitted by voice mail.
Kidder, who doesn't divulge his name or educational background for fear of malpractice, admits he has a medical background and "a lot of experience with neurology and sexual anatomy." He said the lack of comprehensive sexual advice on the market inspired him to create a radio podcast where discussion can be more explicit and to-the-point than it can on video.
"It's easy to have a conversation about sex; it's difficult to show things that will be acceptable to a large audience," he said. "I can't just show a vagina. I can talk about one, though."
With an average of 28,000 downloads per show, "Sex Is Fun" has growing fan bases in the United States, Australia and Britain. Doolittle said it's one of the better outlets for advice on the Internet.
"The guy has some great information and it's always great to hear a guy speaking sincerely," she said about Kidder. "Some guys are really going to relate to him."
But she cautioned that with "Sex Is Fun" -- as with any sex advice show on the Internet, TV, radio or elsewhere -- consumers should think before they act. "Sex Is Fun" drives this home with a disclaimer at the start of every episode saying, "Please use common sense and if you don't have any, stop listening now."
Laura Berman, director of the Berman Center, a Chicago sex health care facility, and Jen Berman's sister, said that what might sound tantalizing on air may not work out in the bedroom, especially if there are deeper issues at play.
"Take the information, use it, enjoy it, but take it with a grain of salt," she said. "Position? Who cares. Stripping for your partner? Go for it. But when it comes to how do you repair the trust in your relationship after an affair, or how do you achieve orgasm if you have trust issues in the bedroom -- if there are more psychological issues, you should see a professional."
