I wonder how many women have actually been confirmed.
I guess, since there's like 200 different continuities now, we should specify. I know that Post-Crisis Batman actually never had sex with Catwoman, as was made clear in Hush. The famous incident on the roof in the New 52 was probably their first time ever in canon, apart from the Earth-Two versions being married with a child. Anyone know what issue that was, anyway?
So mainstream comics, I can only think of Talia and Catwoman as confirmed.
