I take it that this is some sort of irreducible complexity kind of argument. You know, the one where there are so many interdependent parts needed that evolution could not possibly have done it. From your opening post it would seem that this is how you view things. But as several others have pointed out, everything leading from asexual to fully sexual reproduction (male and female) would not have happened in one generation. There would have been a precession of changes taken place over multiple generations. (BTW, You should not have dissed Mr Jack's imaginitive suggestions so easily. There was simply an attempt to show you HYPOTHETICALLY how this could have happened.).
The reasoning in your opening post was flawed, but even IF your statements were valid, they might not necessarily be a huge problem. In fact, points 3-8 could in fact be fulfilled by the organism in which that one original mutation occurred, simply splitting in two as per usual and then mating with itself. Boom, more progeny and more potential mates (but then, just like you did in your original post, I'm just rambling here).
