In some instances, size does matter--especially when you're talking 20,000 square feet. At $4.28 per video for two nights with a $50 per movie deposit, SexWorld's gargantuan selection of flesh in motion can be a bit daunting for the neophyte who doesn't know a double-D feature from a triple-X film. But since even newbies are free to browse the aisles 24 hours a day, seven days a week, trying to guess the videos' contents is part of the fun. A helpful hint: The haircuts on the front of the box are almost always a dead giveaway as to movie quality. Any cover that's devoid of mullets and frizzy perms is almost sure to hold superior contents. Though the value of the bald guys is something you'll have to figure out for yourself.
