The plant has obviously deviated from the normal course of photosynthesis to that of devouring bugs. Was sunlight really such a difficult thing to keep using? Of course, eating flies only benefits the plant. What genetic variation has to occur to include a method of catching something it has no way to recognize or plan for? Here is your problem. Any variation, if the plant could plan that far in advance, include all of the necessary devices to catch a bug. In cellular terms , this must have been something like jumping right out of the ground and singing Hello Dolly! Upwardly mobile decisions is not a possibility in evolution, as obviously, there have to be similarities in species before they can reproduce. There can be NO gradual introduction of accidental variations to create this plant. All of the functions of such a mechanism would have to be planned for in advance, stored into a genetic memory, and then implemented into some usable form which can be reproduced with the advantage of an equally advanced mate. Sound impossible? It is! Try another theory!
Number 1: The Venus Flytrap - fly relationship is predation, not symbiosis. The relationship isn't particularly beneficial to the fly...
Number 2: The Venus Flytrap still performs photosynthesis, its metabolic pathway isn't primarily gathering carbon compounds from the insects as an animal would be. This and other insectivorous plants grow in nitrate poor soils and primarily harvest nitrogen compounds from the insects.
If you want an idea of how this may have evolved look at other insectivorous plants such as the Pitcher. Indeed you might take the time to research Nitrate fixation before posting any more of this claptrap (Or do I have to Google that for you again?)
Back to sex; More primitive organisms are frequently hermaphroditic,
We've actually observed species develop sexual reproduction as a response to genetic damage in the irradiated zone at Chernobyl.
