SEX is on the brains of former Men’s Fitness editor Neal Boulton and his wife, Claire. The openly bisexual couple are shooting scenes around town this week for reality show “Bastard Life,” which is based on Boulton’s Web site and being shopped to networks. “We’re gathering 20 rock groupies in a studio for their Top 10 tips, demonstrated, for getting the lead singer of any band to [bleep] you,” Boulton said. “And we’ll be testing out the toys at Babeland in SoHo. Hey, anything to make our viewers better in bed.”
