Please, please any and all, show me any textual proof to the contrary that SS's have anything other than cocks. Please. Then this good be a debate. But, its not there is zero evidence other than SS's have penises.
And, whats even more confusing to me is that you guys who claim otherwise, don't get that this is a thematic choice. All throughout this series, and I think this is why Bakker was so confused when being called out by feminists, he made them this way as a statement, so to say, of the male mind. Meaning, it takes being a male, thus having a cock, in order to act in these ways. I won't claim to know exact what his point was, because I don't, but it's something along those lines. SS's all have penises for a reason, and it's an author's choice behind that. Indeed, it would be a great question, because you'll get something way more articulate than I can offer. Though I think it runs along those lines.
