I will note that Filament is targeted primarily towards heterosexual women. Although I'm bisexual, this isn't a dealbreaker for me, especially because the editors are clearly more interested in what's sexy than following specific gender configurations. For example, issue 5 contains a M/M story as well as F/M configurations. Still, they have a target audience in mind.
Although pricey for U.S. readers (Filament is based in the U.K. and a subscription cost me nearly $40), it's well worth the cost. This is one of the best magazines I have come across in my life, and one of the few I'm willing to shell out money to read.
