Nina Hartley, hands down. She just has something 99.9% of the other ladies don’t and it makes watching her videos so much more entertaining and arousing. It’s evident that she loves what she’s doing; she loves sex and she loves being a part of turning other people on. Not only that, but she is one of the few people in her position who is also out there trying to educate on better sex practices. There’s a video you can Google where she gives a hands-on lesson on cunnilingus—both hot and educational—something I feel every person who sleeps with women should watch.
Lastly, she is an awesome person and cares a lot about her fans—as I said, she is very interested in the fact that what she does affects the sex lives of those who watch. I’m a member of a fan group on a fetish site and she personally replies to all the gushy fan letters posted in her group.
