It wasn't Hasbro who said that TF are sexless, but a writer. Hasbro didn't write the CoP. Even so, again, it probably meant for the AC. Also that book contradicts itself. Only sexed beings do romance. It was mating that gave birth to romance. Anyway if it was all for TFSU then Springer and Rodimus had wasted their time fight over Arcee. Sexless beings won't fight over a girl.
