Kiss bassist Gene Simmons insists his open relationship with girlfriend SHANNEN TWEED works because she understands his need to have sex with lots of women. Simmons and the former Playboy Playmate have been "happily un-married" for 22 years and he recently ranked third on Maxim magazine's Living Sex Legends countdown. He explains, "Ignore the fact that God has given you a blueprint that you're going to manufacture billions of sperm every single day. "A guy doesn't have a choice in that. He also has testosterone going through his system. "(Women) make one or two eggs per month, and you want to torture us because we're not like you." The LICK IT UP singer hopes to shed some light on the battle of the sexes in his new reality show FAMILY JEWELS.
