The animated movie put it out there but the comics retconned that aspect.
It is also worth pointing out that in the comics the sex act has never been shown/implied as anything but consensual. The conception is where the problem of rape arises. Talia put something in their drink to ensure conception.
I'm not a fan of Talia sleeping with Bruce or Talia spiking Bruce's drink to guarantee pregnancy. I'm also not a fan of if we ignore it might go away. DC should address the Talia situation and retcon her ambiguous presentation as sex criminal/child molester.
