yes there quite a few, but it depends what choices you make. i think all of them are avoidable assuming you choose right(or wrong), but there is unskippable nudity at points through-out the game. in terms of actual sex scenes im going to guess...7 or 8?
Currently playing: Darkness 2 - Persona 4 - KoA: Reckoning - Alan Wake
@Dekou either you havent played the god damn game or then you played it all wrong. EACH new act has a new town with new prostitutes you can all pay for and watch sex scenes + by simply going through the game you see triss / have sex with her 2-3 times AND also can have sex with the short-haired blonde girl. (cant remember her name)
