Why did you find the sexual aspect of Octavia and Servillia's relationship objectionable?

People of both sexes have used erotic means to control others for centuries. Servillia was full of hate and out for vengence. I always wondered why Caesar was so foolish about the women he dallied with. many were as powerful, as cunning, as ruthless and dangerous as he himself wwas.

Atia's behavior as well is calculating and she used Octavia everybit as much as Servillia did...and her brother Octavian will use her. Although there is no evidence per se of the sexual use of Octavia by Servillia, it does seem not far fetched in context of the times...at least for me.
