The novels aren't the video games, Geralt doesn't fuck everything that moves. Lies and slander.
Over all the books, thinking about occasions of intercourse with wamens other than Yen:
- 1 female bodyguard of the dragon villenwhatshisname, that was either before he even came together with Yen or it was when they had broken up
- 1 Triss, the result of Triss using magic so hardly his fault, also happened when he had broken up with Yen (otherwise Triss wouldn't have done it)
- 1 Shani (relationship with Yen was over as after Thaned it was assumed she was among the betrayers, only later it became known she was held hostage in petrified/compressed form by F. Findabair)
- 1 nilfgaard sorceress, same timeframe when he still thought Yen had betrayed them
- 1 melitele priestess when Geralt was gravely injured being cured in the temple by Nenneke, that priestess just came in in the middle of the night started working the shaft... what was he supposed to do, fend her off? Wrestle her to the ground and call the police?
- that bitch who was leading the bandits in Blaviken which Geralt later butchered, I assume this was before he even knew Yen but I'm not sure
This is all I remember and this spans a timeframe of like 2 decades at least. What else was there?
