It might work though. Total anonymity, watching your favorite guys undress "only for you"..
Women feel the temptation of erotica just like the male audience, only social pressure is higher to admit to it (like buying erotic content with credit cards or paypal accounts could result in someone finding out about it).

This project however faces higher barriers like small audience with bitcoins ("Females, where art thou!?"). Guys to undress (anonymously) however should be around in sufficient numbers, given the vast crowd of bitcoin geeks. Once this starts to pick up steam, it could grow..

Femal audience centered erotica products is such an underdeveloped market on the net anyways. Whats the major obstacle for it to take off?
